Answer:C
Step-by-step explanation:
The correct answer is c. To carry out this calculation, we begin by describing the sampling distribution of the sample proportion. The sample size is n=50 and the population proportion of teachers who made an apparel purchase is .56. Shape: because np=(50)(.56)=28 and n(1-p)=(50)(.44) are both at least 10, the shape of the sampling distribution of the population proportion is approximately normal. Center: p=.56. Variability: the standard deviation of the sample proportion is approximately .0702. normalcdf(loser: .6, upper: 1000, mean: .56, SD: .0702)=.284.

• The lower quartile is the line that is on number 16 on the number line
22-16 = 6 and that’s your IQR!
