b) Find the test statistic, Z0(round to two decimal places as needed)C) Find the P-Value (round to three decimal places as needed) In a survey, 41% 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 180 pet owners anddiscovered that 72 of them spoke to their pet on the telephone. Does the veterinarian have a right to be skeptical? Use the a = 0.1 level of significance.Because npo (1- Po)V10, the sample size isV 5% of the population size, and the sampleV the requirements for testingthe hypothesisV satisfied.(Round to one decimal place as needed.)

Given, Hypothesised population proportion, p0= 0.41 Number of favorable cases (X) = 72 Sample…

Is the average time to complete an obstacle course longer when a patch is placed over the right eye than when a patch is placed over the left eye? Thirteen randomly selected volunteers first completed an obstacle course with a patch over one eye and then completed an equally difficult obstacle course with a patch over the other eye. The completion times are shown below. "Left" means the patch was placed over the left eye and "Right" means the patch was placed over the right eye.
