A suggestion is made that the proportion of people who have food allergies and/or sensitivities is 0.42. You believe that the proportion is actually greater than 0.42. The hypotheses for this test are Null Hypothesis: p ≤ 0.42, Alternative Hypothesis: p > 0.42. If you select a random sample of 25 people and 17 have a food allergy and/or sensitivity, what is your test statistic and p-value?

Question 8 options:

1)

Test Statistic: 2.634, P-Value: 0.004

2)

Test Statistic: -2.634, P-Value: 0.996

Your friend tells you that the proportion of active Major League Baseball players who have a batting average greater than .300 is different from 0.79, a claim you would like to test. The hypotheses here are Null Hypothesis: p = 0.79, Alternative Hypothesis: p ≠ 0.79. If you take a random sample of players and calculate p-value for your hypothesis test of 0.0037, what is the appropriate conclusion? Conclude at the 5% level of significance.

Question 9 options:

1)

We did not find enough evidence to say a significant difference exists between the proportion of MLB players that have an average higher than .300 and 0.79

2)

The proportion of active MLB players that have an average higher than .300 is significantly less than 0.79.

3)

The proportion of active MLB players that have an average higher than .300 is significantly larger than 0.79.

Your friend tells you that the proportion of active Major League Baseball players who have a batting average greater than .300 is greater than 0.51, a claim you would like to test. The hypotheses here are Null Hypothesis: p ≤ 0.51, Alternative Hypothesis: p > 0.51. If you take a random sample of players and calculate p-value for your hypothesis test of 0.9482, what is the appropriate conclusion? Conclude at the 5% level of significance.
