- Discuss the assumptions for one-sampled t-test and why they are important.True or False: A professor computed the sample average exam score of 20 students and used it to estimate the average exam score of the 1,500 students taking the exam was an example of inferential statistics. Select one: True FalseHere is a picture of each sample that indicate each summary statistic. However, Write a sentence interpreting the meaning of each number in the five number summary: Min, Q1, Median, Q3, Max. This was my interpretation of the five number summary and the red highlights were in correct, can someone help me find what I did wrong to solve this.
- Suzette does an experiment where she collects date from 5 women snd obtains the scores: 4, 4, 5, 2, 5. She hypothesizes that the population mean for the population from which these scores are drawn is 3. She wants to test whether this hypothesis is true. What is the alternative hypothesis she is testing?The first blank for both questions is: "estimate of the standard ('distance' or 'score' or 'mean')" Second blanks: "...between a ('sample mean' or 'sample mean difference' or 'score')" Third Blanks: "...and the ('population mean difference' or 'population mean' or sample mean')" The choices are the same for the corresponding blanks, first, second and third.A reporter writing for a national newspaper claimed that representatives of school districts were falsely reporting their students’ performance on standardized tests. Over 90% of the nation’s school districts report that their students are performing above the national average, and the reporter claimed that isn’t possible. It is possible. a) Provide a list of 10 numbers for which 90% are above the mean. b) What can you infer about the nation’s school districts if 90% of them really are performing above the national average?
- What is the conclusion? What is your conclusion? -There is no evidence to suggest a difference. -There is a difference in newborns' APGAR score based on whether the mother smoked or not. -Newborns whose mothers didn't smoke have higher APGAR score than newborns whose mother did smoke. -Newborns whose mothers didn't smoke have lower APGAR score than newborns whose mother did smoke.erik, a tourism expert, is researching the number of overnight stays at two large hotels. He collected data for 30 days and calculated that the average number of overnight stays in one hotel was 135 nights and the standard deviation was 22 nights, while in the other hotel the average was 22 nights. mean) 142 and the standard deviation 18 nights. erik used an appropriate hypothesis test to examine whether there was a difference in the distribution of the number of overnight stays in the two hotels (e. Used an appropriate hypothesis test to test if there is a difference in the variance in overnight stays at the two hotels). What is the value of the test statistic? 1.22 0.82 0.95 1.49 0.67Rabbani company is a company that sells Muslim clothing. In their products for sale, there are two types of veil production different. The production manager stated that both types have the same percentage of damage/defects.

- There are 3 parts to this question!! Answer each part in a separate blank! The average price per square foot for a home in a large county in a certain state is $225. The council of a country town wonders if the mean price of the homes in their town is less than the mean price of the homes in the county. The town council selected a random sample of 9 homes that have recently sold in their town. They found the price per square foot and want to perform a hypothesis test at the 0. 05 significance level. The data is listed below. 221.4 213.1 219.1 229.6 220.7 224.4 221.6 217.8 223.9 1. Calculate the test statistic and the P-value. 2. What is the decision at the given significance level? 3. What do you conclude?Give an example problem for the topic Inference about Two Sample Means with Large Sample and solve it. Kindly show all the necessary information to solve the problem.3 A researcher wants to determine the mean income of adults in a particular state. She decides to take a random sample of 1525 citizens with a driver's license from the registry maintained by the Department of Motor Vehicles in that state, and record their incomes. Which one of the following statements is NOT correct? * The sample would be biased since some people without a license may be too poor to own a car and others may choose to use public transportation The sample would not be representative of adults, since teenagers would be included in the sample. Taking a bigger sample from the registry would solve any problems with possible bias People who had recently moved from another state may not yet be included in the DMV registry.
