A USA Today article claims that the proportion of people who believe global warming is a serious issue is 0.5, but given the number of people you've talked to about this same issue, you believe it is greater than 0.5. The hypotheses for this test are Null Hypothesis: p ≤ 0.5, Alternative Hypothesis: p > 0.5. You take a random sample and perform a hypothesis test, getting a p-value of 0.3256. What is the appropriate conclusion? Conclude at the 5% level of significance.

Question 6 options:

1)

We did not find enough evidence to say a significant difference exists between the proportion of people who believe global warming is a serious issue and 0.5

2)

The proportion of people who believe global warming is a serious issue is significantly larger than 0.5.

3)

We did not find enough evidence to say the proportion of people who believe global warming is a serious issue is less than 0.5.

4)

We did not find enough evidence to say the proportion of people who believe global warming is a serious issue is larger than 0.5.

5)

The proportion of people who believe global warming is a serious issue is less than or equal to 0.5.

Answer #1

Ans : We did not find enough evidence to say the proportion of people who believe global warming is a serious issue is larger than 0.5.

(since the P-value =0.3256 > 0.05, we fail to reject H0)

Your friend tells you that the proportion of active Major League Baseball players who have a batting average greater than .300 is different from 0.74, a claim you would like to test. The hypotheses here are Null Hypothesis: p = 0.74, Alternative Hypothesis: p ≠ 0.74. If you take a random sample of players and calculate p-value for your hypothesis test of 0.9623, what is the appropriate conclusion? Conclude at the 5% level of significance.

A researcher claims that more than 75% of the adults believe in global warming. Mimi conducted a survey on a random sample of 200 adults. The survey showed that 155 adults in the sample believe in global warming. Assume Mimi wants to use a 0.05 significance level to test the researcher’s claim. (a) What is the appropriate hypothesis test to use for this analysis? Please identify and explain why it is appropriate. (b) Identify the null hypothesis and the alternative...
