8. A computer company claims that the lifespan of its batteries is 2.7 years. The population standard deviation is 0.85 years. A sample of 25 batteries was tested, and their mean lifespan was 3.1 years. Using a 95% confidence level, determine if the company's claim is correct. Fail to reject the null hypothesis. There is enough evidence to oppose the company's claim. Reject the null hypothesis. There is enough evidence to oppose the company's claim. O Reject the null hypothesis. There is not enough evidence to oppose the company's claim. O Fail to reject the null hypothesis. There is not enough evidence to oppose the company's claim.

We are interested in seeing if there is a difference between how long women and men spend shopping at Costko-K. Men spend an average of 48 minutes in our store with a standard deviation of 22 minutes. Women spend an an average of 39 minutes in our store with a standard deviation of 9 minutes. The sample size for men is 250 and the sample size for women is 300. Test the hypothesis at a 95% confidence level. Show your calculations and explain your findings.
A researcher tests whether listening to music while taking an exam has any effect. The population mean of people taking an exam while not listening to music is 50, with a standard deviation of 12. The researcher tests a sample of 57 people who listen to music while taking an exam and they produce a mean of 54.36. Using a one-tailed test with a p value of .05, the critical value is -1.65 and 1.65. Make a decision about your hypothesis.
A quiz related to digital knowledge was conducted. The quiz had 10 questions and covered topics such as the purpose of browser cookies, phishing scams, and privacy policies. The survey was given to 50 people. The mean score is 4.1 with a standard deviation of 2.6. We want to know if the data provide evidence that the mean score in the population is lower than 5. We will use alpha = 0.05 to make our decision. What is the null hypothesis for this question? Group of answer choices a. The proportion of people who pass the test is 5. b. The mean test score of the population is 5. c. The mean test score of the 50 people who took the test is 5. d.The standard deviation is 2.6
The u.s census bureau conducts a study to determine the time needed to complete a certain form. The bureau surveys 200 people. The sample mean is 8.2 minutes and there is a known population standard deviation of 2.2 minutes. The population distribution is aimed to be normal. Construct a 99% confidence interval for the population mean.

A sample of 106 body temperatures was taken and the mean was 98.2 degrees F. The population standard deviation is 0.62 degrees. Use a 0.05 level of significance to test the claim that the average body temperature is actually different than 98.6 degrees F. Find the 95% confidence interval of the mean temperature and compare your results.
