2. In a random sample of 360 females, 65% of them favored stricter gun control laws. In another sample of 220 females, 60% of them favored stricter gun control laws. Is there any significant difference between the proportions of male and female who favored stricter gun control laws? Explain your answer. Calculator work

Expert Solution

H0: Null Hypothesis: P1 = P2 ( There is no significant difference between the proportions of male and female who favored stricter gun control laws

HA: Alternative Hypothesis: P1 P2 ( There is significant difference between the proportions of male and female who favored stricter gun control laws

The Test Statistic is given by:

Take = 0.05

From Table, critical values of Z = 1.96

Since calculated value of Z = 1.211 is less than critical value of Z = 1.96, the difference is not significant. Fail to reject null hypothesis.

Conclusion:

The data do not support the claim that there is significant difference between the proportions of male and female who favored stricter gun control laws

Gun Murders - Texas vs California - Significance Test: California had stricter gun laws than Texas. However, California had a greater proportion of gun murders than Texas. Here we test whether or not the proportion was significantly greater in California. A significant difference is one that is unlikely to be a result of random variation. The table summarizes the data for each state. The p̂'s are actually population proportions but you should treat them as sample proportions. The standard error...
