A simple random sample of 320 adults was asked their favorite ice cream flavor. Of the 320 individuals surveyed, 30% responded that they preferred mint chocolate chip. At the 0.05 significance level (α=0.05), test the claim that 25% of adults prefer mint chocolate chip ice cream. The mean of the sampling distribution of the sample proportion (assuming the null hypothesis is true) is equal to 0.25. What is the standard deviation of the sampling distribution of the sample proportion (assuming the null hypothesis is true)?
