Question

Use the t-distribution table to find the critical value(s) for the indicated alternative hypotheses, level of significance

alphaα, and sample sizes n 1n1 and n 2n2. Assume that the samples are random and independent, and the populations are normally distributed. Complete parts (a) and (b).

Upper H Subscript aHa:

mu 1 not equals mu 2μ1≠μ2,

alphaα=0.10,

n 1n1=17,

n 2n2=8

A. Find the critical value(s) assuming that the population variances are equal. B. Find the critical value(s) assuming that the population variances are not equal.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
