An important feature of tablets is battery life, the number of hours before the battery needs to be recharged. The data shown in the table below contain the battery life of 10 WiFi-only and 10 3G/4G/WiFi 9- through 12-inch tablets. Complete parts (a) through (c). WiFi-only 3G/4G/WiFi S 49 29 35 31 49 70 50 60 57 53 47 26 34 57 58 27 35 33 50 60 a. Assuming that the population variances from both types of tablets are equal, is there evidence of a difference in the mean battery life between the two types of tablets? Use o = 0.01. Let u, be the mean battery life for WiFi-only tablets and uz be the mean battery life for 3G/4G/WiFi tablets. Determine the hypotheses. Choose the correct answer below. O A. Ho: H1 2H2 O B. Ho- Hq = H2 Hy : H1 = H2 Hy : Hq # H2 O C. Ho: H1 S H2 OD. Ho- Hq # H2 Hy : H1 > H2 Hy: H1 = H2 Find the test statistic. Test Statistic = (Round to two decimal places as needed.) Find the critical value(S). (Use a comma to separate answers as needed. Round to two decimal places as needed.) Choose the correct conclusion below. Ho- There is evidence that the means differ. b. Determine the p-value in (a) and interpret its meaning. p-value = (Round to three decimal places as needed.) Interpret the p-value. Choose the correct answer below. The p-value is the probability of obtaining a sample that yields a t test statistic than the computed test statistic if there is no difference in the mean battery life between the two types of tablets
