A marketing consulting group reported that the typical person in a certain country spends a mean of 144 minutes (2.4 hours) per day accessing the Internet via a mobile device. In order to test the validity of this statement, you construct a simple random sample with 30 observations. The data is found in the accompanying table. Complete parts (a) through (d) below. Click the icon to view the data table. a. Is there evidence that the population mean time spent per day accessing the Internet via mobile device is different from 144 minutes? Use the p-value approach and a level of significance of 0.05. State the null and alternative hypotheses. OA. Ho μ≤144 H₁: μ>144 OC. Ho: H=144 H₁: #144 Determine the test statistic. The test statistic is (Type an integer or a decimal. Round to two decimal places as needed.) Find the p-value. The p-value is (Type an integer or a decimal. Round to three decimal places as needed.) OB. Ho: 144 H₁: 144 OD. Ho≥ 144 H₁: <144
