The casino would reject/accept the null hypothesis (H0) and accordingly, conclude that the slot machine does or does not deliver the claimed win rate of 5 in 100.

To determine if their slot machine delivers the claimed 5 in 100 win rate, the casino would need to conduct a hypothesis test using the given terms.
The "win rate" refers to the proportion of wins a slot machine is expected to provide out of a certain number of plays. In this case, the slot machine claims to have a win rate of 5 in 100, which is equivalent to a proportion of 0.05.
To test if the slot machine actually delivers this win rate, we will conduct a hypothesis test with the following null (H0) and alternative (HA) hypotheses:
H0: The slot machine's win rate is equal to 0.05
HA: The slot machine's win rate is not equal to 0.05
To perform this test, the casino would need to collect a sample of slot machine plays and calculate the observed win rate. Using an appropriate statistical test, such as a z-test or t-test for proportions, the casino can compare the observed win rate to the claimed win rate of 0.05. If the test result shows that there is a significant difference between the observed and claimed win rates, the casino would reject the null hypothesis (H0) and conclude that the slot machine does not deliver the claimed win rate of 5 in 100.

{-4,2,6,9}

The traditional (parametric) test for a sample mean assumes that the data is normally distributed. If the data is not normally distributed, then this test may not be appropriate. Additionally, the parametric test assumes that the sample size is sufficiently large (usually greater than 30) in order for the Central Limit Theorem to apply.

If the sample size is too small, then this test may not be reliable. Furthermore, if there are outliers or extreme values in the data, then the parametric test may not accurately reflect the true underlying population. In such cases, non-parametric tests may be more appropriate, as they do not rely on assumptions about the distribution of the data. It is important to carefully consider the nature of the data before choosing a statistical test to ensure accurate and reliable results.

Step-by-step explanation:

The area of the circle of radius r centered at the origin is π\(a^{2}\)

Since the circle is symmetrical in relation to the x and y axes, we can calculate the area of a quarter of a circle and multiply it by 4 to get the entire circle's area.

The equation y y = + mn [a 2 - x 2] must be solved.

Y = [a 2 - x 2] = a [1 - x 2 / a 2] is the equation for the upper semicircle (y positive).

Using integrals, we can calculate the area of the circle's top right quarter as shown below.

(1 / 4) Circle's area is equal to 0a a [1 - x 2 / a 2]. dx

Let's replace x/a with sin t to make sin t equal to x/a, dx equal to a cos t dt, and the area is given by

The formula for area of a circle is (1 / 4) Area of circle = 0/2 a 2 (1 - sin2 t) cos t dt

Now that t can range from 0 to /2, we utilize the trigonometric identity [1 - sin2 t] = cos t, which equals (1 / 4) Circle area equals 0/2 a 2 cos2 t dt.

To linearize the integrand, use the trigonometric equation cos2 t = (cos 2t + 1) / 2;

(1 / 4) Circle's area is equal to 0/2 a (cos 2t + 1) / 2 dt.

the integral (1 / 4) be evaluated. Circle's area is equal to (1/2) a2 [(1/2) sin 2t + t]. 0π/2\s= (1/4) π a 2

The circle's entire area is calculated by multiplying by 4.

Area of a circle is equal to 4 * (1/4) a 2 a 2. additional references on integrals and calculus applications.

The values are, e = 2.71828 is the Euler number, μ = 0.898, x = 3, probability = 4.915%

Probability is a branch of statistics that deals with the study of random events and their likelihood of occurrence. It is calculated by dividing the number of favorable outcomes by the total number of possible outcomes and is used to make predictions and estimate the likelihood of future events.

The chance that X represents the number of successes of a random variable in a Poisson distribution is provided by the following formula:

\(P(X=x)\) = (e^-μ * μ^x) / x!

Where, x is the number of successes

e = 2.71828 is the Euler number, μ is the mean in the given interval.

Given that, total of 515 bombs hit the combined area of 573 regions.

The mean hits per region is;

μ = 515/573 = 0.898

We want to find the probability that a randomly selected region had exactly three hits, that is P(X = 3)

\(P(X=x)\) = (e^(-μ) * μ^x) / x!

\(P(X=3)\) = (e^(-0.898) * (0.898)^3) / 3!

\(P(X=3)\) = 0.04915

Therefore, 4.915% probability that randomly selected region had exactly three hits.

A subfield of statistics known as probability studies random events and their odds of happening. It is used to predict the future and determine the likelihood of events by dividing the number of favorable outcomes by the total number of possible outcomes.

The following formula gives the probability that X indicates the number of successes of a random variable in a Poisson distribution:

\(p(X=x)=\frac{(e^{-\mu} \times\ \mu^x)}{x!}\)

Where, x is the number of successes

e = 2.71828 is the Euler number, μ is the mean in the given interval.

As a result, 573 regions were struck by a total of 515 bombs.

The mean hits per region is;

\(\mu=\frac{515}{573}\)

\(\mu= 0.898\)

P(X = 3) stands for the probability that a randomly chosen region contained precisely three hits.

\(p(X=x)=\frac{(e^{-\mu} \times\ \mu^x)}{x!}\)

\(P(X=3)=\frac{e^{-0.898}\times\ \(0.898^3 }{3!}\)

Answer:

a) 10 yards and 10\(\sqrt{3}\) yards

Step-by-step explanation:

The intersection of the support beams in the middle form four right angles, since all four sides are equal.  Because you know two angles of the triangle on the right hand side (90° and 30°), you can calculate the third angle (given that a triangle has 180°):

180°-90°-30° = 60°

This is a 30-60-90 triangle (if you don't know what that is, you can look it up).  In a 30-60-90 triangle, the hypotenuse is 2x.  In this case, the hypotenuse is 10 yards, so you can set up an equation given that information:

2x = 10

x = 5

Now that you know x of the 30-60-90 triangle, you can solve for the other two sides of the triangle.

The side directly across from the 30° angle is just x, which is equal to 5.  The side directly across from the 60° angle is x\(\sqrt{3}\), which in this case would be 5\(\sqrt{3}\).

Because you want the full length of both beams, you'd multiple both sides by two to get the length of both entire beams:

5*2 = 10

(5\(\sqrt{3}\))*2 = 10\(\sqrt{3}\)

The work done in stretching a spring from its natural length to 11 inches beyond its natural length is 12.6 foot-pounds. This can be calculated using the following formula:

W = ∫_0^x kx dx

where W is the work done, x is the distance the spring is stretched, and k is the spring constant.

The spring constant can be found using the following formula:

k = F/x

where F is the force required to hold the spring stretched and x is the distance the spring is stretched.

In this case, F = 6 lb and x = 8 inches = 2/3 ft. Therefore, the spring constant is k = 90 lb/ft.

The work done can now be calculated using the following formula:

W = ∫_0^x kx dx

= ∫_0^2/3 * 90 * x dx

= 30 * x^2/2

= 30 * (2/3)^2/2

= 12.6 foot-pounds

Therefore, the work done in stretching the spring from its natural length to 11 inches beyond its natural length is 12.6 foot-pounds.
