Example is given below. I am given an example for hypothesis test for a mean. Please find Red underline Red box and black underline in the given example , these are the areas in the given question which determines we need to conduct a mean test. Since sample size n = 100 is greater than 30 , we can conduct a single sample mean Z test (Normal test).

Calculator feature:

STAT<TEST<Z-TEST(option 1) STATS feature on TI-84 helpful for this test.

Steps :

On TI-84 calculator

Go to STAT<TEST<Z-TEST(option 1)
Choose STATS
Enter in Claim
Enter in population standard deviation
Enter summary statistics (STATS)
Choose your alternative hypothesis

Give an example from a future Health Profession of a mean or a proportion for which you would like to do a Hypothesis Test. As shown in the text your Null and Alternative hypothesis MUST include the symbol for a Population parameter along with your hypothesized claimed numerical value for this parameter. Then discuss the ramifications of making a Type I Error and a Type II Error in the context of your stated Null and Alternative Hypotheses.

Hypothesis Test Example For Proportions: What proportion of people do not drink alcohol? You believe that the proportion of people in the U.S.A. who do not drink is less than 15%. To determine if you are correct, you take a SRS of 400 U.S. residents, and find the proportion of people who do not drink in your sample is 0.22. Conduct a hypothesis test at the 5% significance level. A. Write the hypotheses for the test. B. Check the assumptions...

If we were to conduct a hypothesis test to test if a population proportion of a certain event is 0.2 versus the alternative that it is greater than 0.2 and we sampled 100 people, what would the probability of a Type I Error be if we were to use the arbitrary decision rule to reject Ho if more than 30 units in the sample had the event (not the way we tested hypotheses in class)? What would the probability of...

Write a hypothesis test problem using the problem below. You believe that the population mean number of times that adults go to the gym each week is less than 2.5. You spoke with 10 people and found that they went to the gym 2, 3, 5, 3, 0, 1, 7, 3, 0, and 3 times last week. You then would choose to test this hypothesis at the .05 significance level. Assume a random sample.

Hypothesis Test - Made up problem: The population mean for hours of Netflix watched by individuals each week is less than 3. We spoke with seven random individuals and asked how many hours per week they watch Netflix. The results were 4, 0, 6, 2, 3, 3, and 6 hours in the last week. Test this hypothesis with a significance level of .05.
