need the last part. is it right? In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6989 subjects randomly selected from an online group involved with ears. There were 1306 surveys returned. Use a 0.01 significance level totest the claim that the return rate is less than 20%. Use the P-value method and use the normal distribution as an approximation to the binomial distribution.Identify the null hypothesis and alternative hypothesis.O A. Ho: p= 0.2Св.

Ho: p#0.2H1:p= 0.2The test statistic is z = - 2.75.(Round to two decimal places as needed.)The P-value is 0.003(Round to three decimal places as needed.)Because the P-value isless thanthe significance level,rejectthe null hypothesis. There is insufficient evidence to support the claim that the return rate is less than 20%.
