1. A scientist has developed a theoretical model for predicting eye color. After examining a random sample of parents, he predicts the eye color of the first child. The table found below lists the eye colors of offspring. On the basis of his theory, he predicted that 87% of the offspring will have brown eyes, 8% will have blue eyes, and 5% will have green eyes.

	Blue Eyes	Brown Eyes	Green Eyes
observed frequency	17	132	0
expected frequency	11.92	129.63	7.45

Use chisq.test function in R andtest the claim that the actual frequencies correspond to his predicted distribution, at a 0.05 significance level. PLEASE PROVIDE A SCREENSHOT OF THE R OUTPUT FOR THIS TEST.

2. There is a drug designed to lower systolic blood pressure, called captopril. When subjects were treated with this drug, their systolic blood pressure readings (in mm Hg) were measured before and after the drug was taken. Results are given in the table below. Using a 0.01 significance level, and determine if is there sufficient evidence to support the claim that captopril has an effect on systolic blood pressure? Explain in a sentence why statistical methods (Z-interval, Z-test, T-interval or T-test -cannot be used for this problem) Then, use the sign test to conduct the required test.

Please show all the work.
