Read the situation. Then write...

Read the situation. Then write the hypotheses in correct mathematical notation. Do not conduct any statistical tests. Just write the hypotheses. Insert your answers between the problems.

Here are some things to keep in mind:

1) On the Hypothesis Testing Worksheet, all you need to do is write the null and alternative hypotheses situation.

2) The null hypothesis will always be “=”.

3) You can use either "≠" or “not =” for “does not equal”. Greater than and less than is “>” or “” or “<” (one tailed test).

5) When determining what the null and alternative hypotheses are, realize that the alternative is the new information, what you are trying to prove. The null is what has been believed to be true up until now.

My questions are:

3) In a speech to the Chamber of Commerce, a city councilman claims that in his city less than 15% of the adult male population are unemployed. An opponent in the upcoming election wants to test the councilman’s claim.

4) The councilman is starting to get worried about the upcoming election. He has enjoyed 63% support years, but the political climate has been changing. He wants to know if his support has changed.

Statistics Problems

1) Ask 10 people (try to get 5 males and 5 females) the following questions

A) Their ages

B) How many vitamins they take daily

C) How many carbonated sodas they drink each day

D) How many alcoholic beverages they drink per month

E) Write your own question. Ask your participants if they agree with something or if they do something. , you may want to ask them if they eat popcorn when they go to the movies or if they support a political issue. It must be a yes/no question.

SAVE YOUR DATA - You will use the data you gathered above problems below and more question in future weeks.

Practice Problems:

1) Use your data from above. This week assume that historically the average person takes 3 vitamins on a daily basis. Conduct a hypothesis test analysis to determine if 3 is still the correct average number. Write your hypotheses in correct statistical notation. Finally use the important numbers from your output to explain your results. Use alpha = 0.05. Post only the relevant numbers, not all of the output; then explain your results.

2) Use your data from above. Analyze if more than 58% support an issue or partake in an activity. (Question E above). Write the hypotheses. Show the relevant numbers. Then explain your results. Use alpha = 0.05.
