Explain how to conclude when you would reject the null hypothesis based on a p-value. Give a numeric example.

Explain what type of a probabilistic result is conveyed by the P-value.

A researchers claims 45% of couples have children. They conduct a hypothesis test and reject the null hypothesis. What type of error could have been committed here? Type 1, type 2, or power if the test?

Which of the following are the signs which can be found in the null hypothesis? > II V VI

According to the Minnesota Baccalaureate Psychomotor Skills Test (2008) your patient has significantly greater psychomotor skills than the average patient. Which of the following results would be appropriate to see with this finding? a-Z=1.36 (p=0.01) b-Z=5.67(p=0.08) c-Fail to reject the null d-Z= -1.98 (p=0.02) why is the answer a? and what is a trick to remember with p values? i understand that it is 0.05 or 5% chance of error

In each part, we have given the significance level and the P-value for a hypothesis test. For each case determine if the null hypothesis should be rejected. Write "reject" or "do not reject" (without quotations). Double check that you have'typed your answers correctly (no spelling errors) BEFORE you submit. In order to allow you more than one attempt at this problem, the problem will not tell you which part(s) are correct if you do not get all parts correct. (a) a = 0.01, P= 0.06 answer (b) a 0.06, P = 0.06 answer. (C) a = 0.07, P = 0.06 answer.

A researcher believes that more than half of college students average less than 6 hours of sleep per night during the week.  Suppose she collected data to test her belief and found a p-value  < 0.0001.  Fill in the information for her hypothesis test below. Type of test:   a. Left-tail   b. Right-tail   c. Two-tail

An opinion poll asked a random sample of high school couples in the United States whether they believe they will marry their high school sweetheart. A researcher believes more than 25% of high school couples believe they will marry. Which null and alternative hypotheses should be used to test this claim? O Ho: p = 0.25, Ha: p > 0.25 O Ho: p = 0.25, Ha: p 0.25, Ha: p = 0.25 O Ho: P = 0.25, Ha: p > 0.25
