In the pаst, Disneylаnd believed thаt 34% оf visitоrs buy a churrо. To see if that has changed, Disneyland plans to choose a random sample of 350 visitors. 1. Assuming that the 34% is correct, what is the mean and standard deviation in the number of visitors in groups of 350 that would be expected to buy a churro? Where rounding is necessary, round to one decimal places. Mean = [mean] visitors Standard deviation = [sd] visitors 2. Describe the sampling distribution of the sample proportion for samples of size n = 350. The sampling distribution is [norm] with a mean
