She samples 70 technology companies and finds that 60 of them have Twitter accounts. Can she conclude that more than 73% of technology companies have Twitter accounts? Use the α = 0.01 level of significance with the P-value method and Excel. Part 1 of 5 (a) State the null and alternate hypotheses. Ho: p = 0.73 H₁:p> 0.73 This hypothesis test is a right-tailed Part: 1 / 5 Part 2 of 5 test. (b) Compute the test statistic. Do not round intermediate steps. Round the answer to two decimal places.
