In a random sample of 360 women, 65% favored stricter gun
control laws. In a random sample of 220 men, 60% favored stricter
gun control laws. Test the claim that the proportion of women
favoring stricter gun control is higher than the proportion of men
favoring stricter gun control. Use a significance level of
0.05.
TWO PROPORTIONS
In a random sample of 360 women, 65% favored stricter gun
control laws. In a random sample of 220 men, 60% favored stricter
gun control laws. Test the claim that the proportion of women
favoring stricter gun control is higher than the proportion of men
favoring stricter gun control.

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
3. In a recent survey of gun control laws, a random sample of
1000 women showed that 65% were in favor of stricter gun control
laws. In a random sample of 1000 men, 60% favored
stricter gun control laws. Test the claim that the
percentage of men and women favoring stricter gun control laws is
the same at α=0.05

A survey of 2000 Californians revealed that 1,350 supported
stricter gun control laws. Develop a 99% confidence interval for
the true proportion of all Californians who support stricter gun
control laws.
