85% of voters in a city are in favor of stricter gun control laws. If 120 voters in the city are randomly selected. Let the random variable X represent the number that favor stricter gun control laws. a) Find the mean, variance and standard deviation of X b) Would it be unusual if 110 of the selected voters favored stricter gun control laws?

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 (SE) is given to save calculation time if you...
