At a major credit card bank, the percentages of people who historically apply for the Silver, Gold and Platinum cards are 60%, 30% and 10% respectively In a recent sample of customers responding to a promotion, of 200 customers, 106 applied for Siver, 54 for Gold and 40 for Platinum. Is there evidence to suggest that the percentages for this promotion may be different from the historical proportions? a) What is the expected number of customers applying for each type of card in this sample if the historical proportions are still true? b) Compute the x statistic c) How many degrees of freedom does the statistic have? a) The expected number of silver card customers is (Type an integer or a decimal)

Researchers wondered if there was a difference between males and females in regard to some common annoyances. They asked a random sample of males and females, the following question: "Are you annoyed by people who repeatedly check their mobile phones while having an in-person conversation?" Among the 505 males surveyed, 171 responded "Yes"; among the 522 females surveyed, 202 responded "Yes." Does the evidence suggest a higher proportion of females are annoyed by this behavior? Complete parts (a) through (g) below. C -0.0484 ő 0 0.0484 (e) Determine the P-value based on the model from part (d). First find the test statistic for this hypothesis test. (Round to two decimal places as needed.)
1. The percentage of 12- to 17-year-olds who reported talking at least once in the past year with their parents about the dangers of drug, tobacco, or alcohol is 60% nationally. A state youth council believes this proportion is higher in their state, where there has been an intense media campaign about this issue. A survey of randomly chosen students from across the state shows 1032 of 1642 students reporting they are having these conversations with their parents. Is there evidence that the percent of students using drugs, tobacco or alcohol in this state is above the national rate?
One hundred adults were randomly sampled and took their BMI and categorize them as Underweight, Normal Weight and Overweight. The data is summarized in the following table. If one of the hundred aults is randomly selected: a) What is the probability that they are 56+ or overweighted? b) What is the probability that they are underweighted or normal weighted? c) Is it correct to say that a randomly selected adult is 1.2 times as likely to be an overweighted as underweighted? Justify your answer.
