Question 1 5 pts In the U.S. only 24% of young adults are financially independent. What is the population proportion p? [ Select ] Suppose we take many random samples of 1000 US young adults. In each sample, we calculate the sample proportion p of young adults that are financially independent. We collect all the sample proportions p and construct a sampling distribution of sample proportions Is the sampling distribution of sample proportions approximately normal? [ Select ] If we take many random samples of n = 1000 US young adults, the mean of the sampling distribution will be #g = p = ? [ Select ] If we take many random samples of n = 1000 US young adults, the standard error of the sampling distribution will be of = p(1-P). = ? [ Select ] n What is the probability that in a random sample of 1000 US young adults, the sample proportion of financially independent young adults is between 0.21 and 0.27? [ Select ]Question 2 5 pts Vets say that 40% of cats are overweight. Suppose we collect a lot of random samples of 25 cats. In each sample, we calculate the sample proportion p of overweight cats. We collect all the sample proportions p and construct a sampling distribution of sample proportions Is the sampling distribution of sample proportions approximately normal? [ Select ] Find the mean and standard error of the sampling distribution with n = 25 cats. [ Select ] and [ Select ] What is the probability a sample of 25 cats will have more than 50% overweight cats? [ Select ] What's the probability a sample of 25 cats will have fewer than 37.5% overweight cats? [ Select ]
