In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6997 subjects randomly selected from an online group involved with ears There were 1309 surveys returned Use a 0 01 significance level to test the claim tha the return rate is less than 20% Use the Pvalue method and use the normal distribution as an approximation to the binomial distribution. Identify the null hypothesis and alternative hypothesis O B. H p<0.2 OA H pr02 H, p=02 H, p=02 OC. H p02 OD. H p>02 H p=0.2 H, p>02 OE H p-02 OF H p=02 H, pr02 H p<02 The test statistic isz (Round to two decimal places as needed) The Pvalue is (Round to three decimal places as needed) Because the P.value is the significance level, the null hypothesis There is evidence to support the claim that the return rate is less than 20%
