For a one-tailed test (lower tail), a sample size of 10 at 90% confidence, t = a. 1.383 b. 2.821 c. -1.383 d. -2.821.
Answers
To find the value of t for a one-tailed test (lower tail) with a sample size of 10 at 90% confidence, we need to consult a t-distribution table or use a calculator that can perform this calculation. The answer to this question is option c. -1.383.
The critical value of t for a one-tailed test at 90% confidence with 10 degrees of freedom is -1.383. This means that the test statistic (t-value) must be less than -1.383 in order to reject the null hypothesis in favor of the alternative hypothesis.
It's important to note that a one-tailed test only considers one direction of the distribution (either the lower or upper tail), while a two-tailed test considers both directions. The choice of a one-tailed or two-tailed test depends on the research question and the hypotheses being tested.
Overall, a one-tailed test with a sample size of 10 at 90% confidence has a critical t-value of -1.383, which means that we can reject the null hypothesis in favor of the alternative hypothesis if the t-value is less than -1.383. Hence, c is the correct option.

Which expression is equivalent to the expression shown below? floor - 1 < 13 a 13 < floor - 1 b 13 >= floor - 1 c floor < 12 d floor - 1 <= 12
Answers
The expression "floor - 1 < 13" is equivalent to the expression shown in option b) "13 >= floor - 1".
The expression "floor - 1 < 13" compares the value of "floor - 1" to 13 using the less than (<) operator.To obtain an equivalent expression, we can rearrange the comparison by flipping the inequality sign and reversing the order of the operands.Therefore, "13 >= floor - 1" is the equivalent expression, which means 13 is greater than or equal to "floor - 1".where the value of "floor" is being compared to 12. By subtracting 1 from "floor" in the original expression and comparing it to 13, we can achieve the same result by directly comparing "floor" to 12.

True or False?
Answers
True. Linux uses a logical directory tree to organize files into different folders. Linux uses a tree-like structure to store and arrange files in directories.
A directory, also known as a folder, is a container for files and other directories. It contains all of the data associated with the files stored in it, such as the file's content and metadata. Linux's directory tree is hierarchical, with directories branching out from the root directory to the other directories.
All of the directories in the tree are related to one another. The top-level directory is the root directory, denoted by a forward slash (/). This directory contains all other directories and files in the file system. As the system administrator, you can create new directories and files in the appropriate folders, assign users and groups to them, and set permissions. Linux directory system provides an organized method for keeping track of files and folders, making it easy to find and manage files. The Linux file system's logical tree structure allows for more secure and efficient access to files. It is an important aspect of the Linux operating system and one that is frequently referenced when dealing with its many features.

Your ghost hunting group is recording the sound inside a haunted Stanford classroom for 20 hours as MP3 audio files. About how much data will that be, expressed in GB
Answers
Answer:
1.152 GB if it will be at 128 kbps quality
Explanation:
So, let's say you choose your mp3 be 128 kbps (kilobits per second).
One byte is 8 bits. So 128 kbps = 16 kilobytes per second.
There is 60*60 seconds in one hour. So 16*60*60 = 57.6 megabytes per hour
Multiply by 20 hours to get your answer: 57.6*20 = 1152 MB = 1.152 GB.
20 hours as MP3 audio files would be about 1.2 GB of data
MP3 audio uses about 1 MB per minute.
20 hours = 60 minutes/hour * 20 hours = 1200 minutes.
Since MP3 audio uses about 1 MB per minute, hence for 1200 minutes:
1200 minutes = 1200 minutes * 1 MB per minute = 1200 MB (1.2 GB)
20 hours as MP3 audio files would be about 1.2 GB of data

In response to the COVID-19 pandemic, Australian federal government developed COVIDSafe app (https://www.health.gov.au/resources/appsand-tools/covidsafe-app) which uses mobile tracking technologies to perform rapid contact tracing. However, these technologies are only effective if the public is willing to use them, implying that their perceived public health benefits must outweigh personal concerns over privacy and security. The current study assessed attitudes towards the COVIDSafe app in a representative sample of the Australian public. Participants were invited to a survey. After providing consent and demographic information, participants were asked about how they perceived the risk of COVID-19, perceived benefits and harms from smartphone tracking. Responses were made on a 5-point Likert scale, where increasing values were associated with greater endorsement of the issue raised in a specific question. Based on the above information, answer the following: 1. What type of study is this? 2. What is the population of interest? 3. (2 mark) What is NOT a variable of interest?
Answers
This study is a survey-based research study. The population of interest in this study is the Australian public. The variable that is NOT of interest in this study could be the participants' gender.
The study described is a survey-based research study conducted to assess attitudes towards the COVIDSafe app in a representative sample of the Australian public. It aims to understand the public's perceptions of the app's benefits and harms related to privacy and security concerns.
This study is a survey-based research study. Surveys are commonly used to collect data from individuals and assess their attitudes, beliefs, and opinions on a specific topic. In this case, the study aims to gather information on attitudes towards the COVIDSafe app.
The population of interest in this study is the Australian public. The researchers aim to obtain data from a representative sample of the general population in Australia. This means that they want to capture the diversity of opinions and attitudes among Australian citizens regarding the COVIDSafe app.
The variable that is NOT of interest in this study could be the participants' gender. Since the study is focused on assessing attitudes towards the COVIDSafe app and the perceived benefits and harms related to smartphone tracking, gender may not be a central variable in this context. Other demographic information, such as age or location, might be more relevant in understanding the attitudes of the population towards the app.
In summary, this survey-based research study aims to assess attitudes toward the COVIDSafe app among a representative sample of the Australian public. The population of interest is the Australian public, and variables related to attitudes, perceived benefits, and harms of the app are of primary interest, while variables like gender may have less relevance in this particular study.
