The proportion of households with pets is estimated to be 85% The proportion of 200 investigated households with pets is 0.78.Is this providing evidence that the 85% estimate is incorrect? Test at 95% confidence level.Hint This is a hypothesis test You need to calculate the test statistic and compare it with the critical value to make your decision and conclusionSelect oneO a No, since the test statistic is larger than the left critical valueO b Yes, since the test statistic is smaller than the left critical valueO c Yes, since the test statistic is more then the positive critical valueO d No, since the test statistic is less than the positive critical value

Given that The proportion of households with pets is estimated to be 85% = P = 0.85 Sample size (n)…
