Assume that the samples are independent and that they hve been randomly selected. A marketing survey involes product recognition in New Yourk and California. Of 682 NEw Yorkers surveryed, 218 knew the product while 192 out of 518 californians knew the product. CAlculate the point estimates for both populations, the pooled sample, and the complement of the pooled sample. At the 0.05 significance level, test the claim that the recpgnition rates are the same in both states. Include your null and alternative hypothesis, the critical vaules, test statistic, P-value, decision about the null hypothesis, and an overall conclusion about the claim in your answer. Draw the z distribution. Construct a 95% confiecne interval estimate of the difference between the two population proportions. Explain how CI supports your decision about the null hypothesis.
