. In an agronomy experiment peanuts with shriveled seeds were crossed with normal peanuts.1 The genetic model that the agronomists were considering predicted that the ratio of normal to shriveled progeny would be 3:1. They obtained 95 normal and 54 shriveled progeny. Do these data support the hypothesized model? Consider the two hypotheses H0 : p = 3/4 and HA : p 6= 3/4, and a significance level α = 0.01. You are going to perform the test in two equivalent ways. (a) A χ 2 test: compute the expected number of observations e1 and e2 under the null hypothesis, compute the chi-squared statistic, anc compare it with a critical value; also find the p-value. (b) A two-sided test of proportions; compute the p-value as well: you should get the same p-value as in part (a).

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
