In a sample of 75 workers from a factory in city A, 8% did not graduate from high school. In a sample of 60 workers from a factory in city B, 10% did not graduate from high school. Can we conclude that there is a difference in the propertions of workers who did not graduate from high school in the two cities? Ise a significance level of 0.05.
Homework Answers
p1cap = X1/N1 = 6/75 = 0.08
p1cap = X2/N2 = 6/60 = 0.1
pcap = (X1 + X2)/(N1 + N2) = (6+6)/(75+60) = 0.0889
Below are the null and alternative Hypothesis,
Null Hypothesis, H0: p1 = p2
Alternate Hypothesis, Ha: p1 ≠ p2
P-value Approach
P-value = 0.6818
As P-value >= 0.05, fail to reject null hypothesis.
There is not sufficient evidence to conclude that the two proportions are different

A decade-old study found that the proportion, p, of high school seniors who believed that "getting rich" was an important personal goal was 70%. A researcher decides to test whether or not that percentage still stands. He finds that, among the 215 high school seniors in his random sample, 143 believe that "getting rich" is an important goal. Can he conclude, at the 0.05 level of significance, that the proportion has indeed changed? Perform a two-tailed test. Then fill in...

Women athletes at the a certain university have a long-term
graduation rate of 67%. Over the past several years, a random
sample of 36 women athletes at the school showed that 22 eventually
graduated. Does this indicate that the population proportion of
women athletes who graduate from the university is now less than
67%? Use a 5% level of significance.

However, out of a random sample of n2 = 101 adult Americans who did attend college, '2 = 47 claim that they believe in extraterrestrials.

Workers at a certain soda drink factory collected data on the volumes (in ounces of a simple random sample of 22 cans of the soda drink. Those volumes have a mean of 12.19 oz and a standard deviation of 0.12 r. and they appear to be from a normally distributed population. If the workers want the filing process to work so that almost alcans have volumes between 12.01 oz and 12 53 oz, the range rule of thumb can be...
