In a survey, 31% of the respondents stated that they talk to their pets on the telephone. A veterinarian believed this result to be too high, so he randomly selected 240 pet owners and discovered that 70 of them spoke totheir pet on the telephone. Does the veterinarian have a right to be skeptical? Use the α = 0.05 level of significance.Because np (1-P₁) = 51.3 > 10, the sample size issatisfied.(Round to one decimal place as needed.)What are the null and alternative hypotheses?Ho: p = 0.31 versus H₁: P < 0.31(Type integers or decimals. Do not round.)Find the test statistic, Zo.Zo=(Round to two decimal places as needed.)less than 5% of the population size, and the sampleis given to be random,the requirements for testing the hypothesis are

The hypothesized proportion is 0.31.
