A survey was used to determine whether more than 10% of the population of the state of Virginia is left-han result was that 18 out of 150 people surveyed were left-handed. Assume all conditions hold. The p-value for this test is 0.2061. If the hypothesis test is conducted at the 0.10 significance level, what d researcher make? A. Reject H0 and conclude that the proportion of left-handers in the state of Virginia is greater than D. Reject H0. There is not sufficient evidence to conclude that the proportion of left-handers in th greater than 0.12. C. Fail to reject H0 and conclude that proportion of left-handers in the state of Virginia is equal t B. Fail to reject H0. There is not sufficient evidence to conclude that the proportion of left-han Virginia is greater than 0.10.

Step 1
The problem describes a hypothesis test to determine if the proportion of left-handers in Virginia is more than 10%. We are given the sample data (18 out of 150 are left-handed), the p-value (0.2061), and the significance level (0.10). We need to determine the Show more…

A hypothesis test is done at the 5% significance level in which the alternative hypothesis is that more than 10% of the population is left-handed. The P-value for the test is calculated to be 0.15. Which statement is correct? (A) We can conclude that more than 5% of the population is left-handed. (B) We can conclude that more than 10% of the population is left-handed. (C) We can conclude that more than 15% of the population is left-handed. (D) We cannot conclude that more than 5% of the population is left-handed. (E) We cannot conclude that more than 10% of the population is left-handed. (F) We cannot conclude that more than 15% of the population is left-handed.

Question 4 (1 point) Select the most appropriate response: A hypothesis test is conducted in which the alternative hypothesis is that more than 10% of the population is left-handed. The p-value for the test is calculated to be 0.40. Which statement is correct? There is little evidence to suggest that more than 10% of the population is left-handed. There is a 40% chance that more than 10% of the population is left-handed. There is a 60% chance that more than 10% of the population is left-handed. There is strong evidence to suggest that more than 10% of the population is left-handed.
