Question

4. A random sample of n 1 equals 125
individuals results in x 1 equals 40 successes. An independent sample of

n 2 equals 160 individuals results in x 2 equals 60

successes. Does this represent sufficient evidence to conclude that

p 1 less than p 2p at the α=0.01level of significance?

Determine the null and alternative hypotheses.

5..

The data table represents the measure of a variable before and after a treatment. Does the sample evidence suggest that the treatment is effective in decreasing the value of the response variable? Use the

α=0.01

level of significance. Complete parts (a) through

(d).
