A scientist wants to perform a t-test that studies the brain weights of football players who have CTE. The scientist comes to you and is worried that the t-test is not valid because the sample size is only 20. Give them some advice on what they should do to proceed with doing a t-test or not.
Homework Answers
here we use t-test to to test the average weight of football players who have CTE
#wieght of football players who have CTE is continious variable and t-test is valid only when sample size is small .thats why you should not worry of sample size .if sample size is large then we use z-test and sample size is small we use t-test .there fore t-test is appropriate to use here
hence here we use t-test

PLEASE HELP! Z-test or T-test? Give a full explanation please! A researcher wants to compare the email use of the employees at one company to the corresponding population. Data is collected on the number of emails received by the company's employees. It will be necessary to use this sample data, as well as population data to determine if there is a significant difference between both. Population Mean number of emails: 25 Standard deviation: 3 Sample Mean number of emails: 20...

PART 2: Which test-statistic, z, t, or neither? A candy factory that produces chocolate bars claims each bar weighs 50 grams, at least that is what is printed on the label. Of course, there is bound to be a little variation. An inspector randomly chooses 9 bars from one day's output of 4000 bars. The average weight of the 9 bars is only 47 grams with an SD of 3 grams. The inspector wishes to test the null hypothesis that...

The One Sample 2 Test ESP A husband and wife claim that they have a special bond that allows them to communicate by ESP. To test this claim, an researcher puts the husband and wife in separate rooms. The husband is randomly shown one of colors: either blue, red, green, yellow or orange. He then is given 5 seconds to use his ESP to communicate the color to his wife. The wife then has to decide which of the 5...
Would it be valid for the sleep researcher to use the repeated-measures t test to test whether playing classical music before going to bed shortens sleep latency
7. Assumptions underlying the repeated-measures t test Suppose a sleep researcher wonders whether playing classical music while getting ready for bed helps people fall asleep faster. She has 20 study participants sleep two nights in the sleep lab. For one of those nights, the researcher has each study participant listen to classical music for 15 minutes before getting into bed. For the other night (the control night), the room is quiet. (The researcher varies which night the study participants listen to...

Which Test those cases should use? A: one sample z-test B: one-sample t-test C: t-test for the difference between means for two related samples D: t-test for the difference between means for two independent samples with homogeneity of variance E: t-test for the difference between means for two independent samples with heterogeneity of variance F: a one sample z-test for proportions (or a chi-square goodness of fit) G: chi-square goodness of fit only (where a one sample z-test of proportions isn’t appropriate) H: a two-sample z-test...

Suppose that Vera wants to test the hypothesis that women make less money than men doing the same job. According to the Bureau of Labor Statistics (BLS), the median weekly earnings for men in the sales and office occupation sector in 2015 was $704. Vera collected median weekly earnings data for women in 2015 from a random subset of 16 positions in the sales and office occupation sector. The following is the sample data. $566, $648, $767, $683, $604, $727,...

Exercise. A researcher wants to test: : What’s wrong with this? Exercise 7.24. Although the Environmental Protection Agency (EPA) establishes the tests to determine the fuel economy of new cars, it often does not perform them. Instead, the test protocols are given to the car companies, and the companies perform the tests themselves. To keep the industry honest, the EPA runs some spot checks each year. Recently, the EPA announced that Hyundai and Kia must lower their fuel economy estimates...
