Test the hypothesis that more than 20% of Indian household actually
liked the taste of the drink (with a significnace of 5%). A team has collected
the samples from 350 houses and found out that 80 have actually liked the taste of
the carbonated drink. Assuming the population mean (with the same null hypothesis) is 20%, then find out the population Standard Deviation in the given data frame?
