2 this question has part a and b Independent random samples were selected from two quantitative populations, with sample sizes, means, and variances given below.| | Population 1 | Population 2 ||-----------------|--------------|--------------|| Sample Size | 48 | 52 || Sample Mean | 10.4 | 8.5 || Sample Variance | 9.5 | 15.42 |A 90% confidence interval for \( \mu_1 - \mu_2 \) is 0.74 to 3.06, and a 99% confidence interval for \( \mu_1 - \mu_2 \) is 0.09 to 3.71. Use these confidence intervals to answer the questions.1. Can you conclude with 99% confidence that there is a difference in the means for the two populations? - Yes. The value \( \mu_1 - \mu_2 = 0 \) is not in the interval which suggests that there is likely a difference between \( \mu_1 \) and \( \mu_2 \). - No. The value \( \mu_1 - \mu_2 = 0 \) is not in the interval which does not suggest that there is a difference between \( \mu_1 \) and \( \mu_2 \). - No. The value \( \mu_1 - \mu_2 = 0 \) is in the interval which does not suggest that there is a difference between \( \mu_1 \) and \( \mu_2 \). - Yes. The value \( \mu_1 - \mu_2 = 0 \) is in the interval which suggests that there is likely a difference between \( \mu_1 \) and \( \mu_2 \).2.

In 2004 it surfaced in Reader's Digest presented as having happened to a teacher at an unnamed community college. Four students walked in halfway through American history test my father was giving at the local community college. "Sorry," they said, "we had a flat tire." An understanding man, Dad said that if they could answer just one question correctly, he would give them each an "A" for the exam. The students agreed. So my father handed each one a piece of paper, placed them in four separate comers and said, "Write down which tire was flat." Kurt Smith What is the probability that these four students would give identical answers if they hadn't had a flat tire? Why?
