Hypertension is when an adult is classified as having high blood pressure (above 130 systolic blood pressureis considered hypertension). Researchers want to know the proportion of adult North Americans (above ageof 18) that have hypertension. Based on a study of 3532 adult North Americans, 1219 of them were classifiedas having hypertension. If we were to decrease our level of confidence, what would we expect to happen to the confidence interval?Get wider/ get narrower/ stay the same?Get narrowerstay the sameGet wider

You want to create a confidence interval for the difference in the percent of people over 40 who took music lessons as children and the percent of people 20-40 who took music lessons as children. You decide to use the Plus Four method. You ask 30 people over 40 and find that 21 of them took music lessons as children. You ask 25 people 20-40 and find that 13 took music lessons as children. Fill in the blanks for what you would put into your calculator's interval function. Have people over 40 be group 1. X1 = n1 = X2 = n2 =
