A group of science students plans to take SRS of 25 days in the year to see what proportion of days sampled have a low below 0 °C in particular city. suppose that 41% of days in the city have a low temperature below 0 °C. Let p-hat represent the proportion of a sample of 25 days with a low temperature below 0 °C.
What are the mean and standard deviation of the sampling distribution of p-hat?
Choose 1

A) up=(365)(0.41)
op= check mark 365(0.41)(1 - 0.41)
B) up=0.41
op= check mark 0.41(1 - 0.41)/25
C) up= (25)(0.41)
op=check mark 25(0.41)(1 - 0.41)
D)up= 0.41
op=check mark 0.41(1 - 0.41)/365
