Previous research indicates that 20% of homeowners do not carry sufficient homeowner’s insurance to adequately protect their investment. An insurance agency conducts a major advertising campaign in an attempt to rectify this situation. After the campaign, the agency randomly surveys 150 homeowners and find that 20 of them do not carry sufficient insurance. Does it appear that the proportion of homeowners without sufficient insurance was less after the ad campaign? State the critical value (CV), test statistic (TS), and decision from the test. (Useα= 0.05.)

◦

CV = 2.3263; TS = –2.04; fail to rejectH0
