- A recent debate about where in the United States skiers believe the skiing is best prompted the following survey of randomly selected skiers. Using α = 0.10, test to see if the best ski area is independent of the level of the skier. Write the hypotheses, calculate the expected counts, check the condition, calculate the test statistic, and use either the critical value approach or the p-value approach to make a conclusion.

She counts 37 women in the park, of whom 24 are wearing face masks, while 14 out of 30 men are wearing face masks. Can she say that there is a significant difference of the percent of each gender who wears masks?
