Suppose the probability is p = 0.4 that a person who purchases an instant lottery ticket wins money, and this probability holds for every ticket purchased. Consider different random samples of n = 24 purchased tickets. Let p = sample proportion of winning tickets in a sample of 24 tickets. (a) Give the numerical value of the mean of the sampling distribution of p. (Round your answer to two decimal places.) Mean = (b) Calculate the standard deviation, s.d. of the sampling distribution of p. (Round your answer to two decimal places.) s.d.(p) = (c) Use the Empirical Rule to find values that fill in the blanks in the following sentence. (Round your answers to two decimal places.) In about 68% of all randomly selected samples of n = 24 instant lottery tickets, the proportion of tickets that will be money winners will be between and (d) Use the Empirical Rule to find values that fill in the blanks in the following sentence. (Round your answers to two decimal places.) In about 95% of all randomly selected samples of n = 24 instant lottery tickets, the proportion of tickets that will be money winners will be between and

Suppose a random sample of n = 350 teenagers 13 to 17 years of age was asked if they use social media. Of those surveyed, 280 stated that they do use social media. Find the sample proportion of teenagers 13 to 17 years of age who use social media. The sample proportion is p= (Round to three decimal places as needed.) ...

Last school year, the student body of a local university consisted of 20% freshmen, 21% sophomores, 29% juniors, and 30% seniors. A random sample of 300 students taken from this year's student body showed the following number of students in each class. Freshmen 84 Sophomores 65 Juniors 86 Seniors 65 We are interested in determining whether there has been a significant change in the distribution of class between the last school year and this school year.If the distribution is the same as the previous year, the expected number of freshmen is _____.   a. 84     b. 87     c. 60     d. 20
