A study is done to test the claim that Company A retains its workers longer than Company B. Company A samples 16 workers, and their average time with the company is 5.2 years with a standard deviation of 1.1. Company B samples 21 workers, and their average time with the company is 4.6 years with a standard deviation of 0.9. The populations are normally distributed.
write the hypothesis in symbolic form.
determine the value of the test statistic.
find the critical value OR the p-value.
determine if you should reject the null hypothesis or fail to reject the null hypothesis.
write a conclusion addressing the original claim.
All work must be shown in order to receive any credit.

A researcher tests the claim that the coronavirus can live on doorknobs for longer than on stainless steel water bottles, on average. (3 pts) Write the null and alternative hypotheses. (3 pts) If the researcher commits a Type I error, that means the researcher rejects the null hypothesis when the null hypothesis is true (i.e. the alternative hypothesis is false). Write the Type I error in context. (3 pts) If the researcher commits a Type II error, that means the...

The claim is that more than 75% of workers are satisfied with their job, and sample statistics include 600 employed adults; with 490 of them saying that they are satisfied with their job. Use a 0.01 confidence interval to test the claim.

A movie company conducts a study to test the claim that the majority of people who watch their movies from 12:00-3:00 are all under 30. They surveyed 30 random people with a mean age of 28 years old, also the population standard deviation for the average viewer is 6 years. What can we conclude about their claim with 0.05 significance? Assume equal variances.

A study is done to determine if students in the California state university system take longer to graduate, on average, than students enrolled in private universities. One hundred students from both the California state university system and private universities are surveyed. Suppose that from years of research, it is known that the population standard deviations are 1.5231 years and 1 year, respectively. The following data are collected. The California state university system students took on average 4.6 years with a...

We want to test the claim that people are taller in the morning than in the evening. Morning height and evening height were measured for 30 randomly selected adults and the difference (morning height) − (evening height) for each adult was recorded in the table below. Use this data to test the claim that on average people are taller in the morning than in the evening. Test this claim at the 0.01 significance level. (a) In mathematical notation, the claim...
