Question

Need help finding the following:

  • Calculate the P Value
  • State conclusion for the test
  • State the conclusion in context of the problem
A simple random sample of size n = 200 drivers were asked if they drive a car manufactured in a certain country. Of the 200 drivers surveyed, 120 responded that they did. Determine if more than half of all drivers drive a car made in this country at the α = 0.05 level of significance. Complete parts (a) through (d). (a) Determine the null and alternative hypotheses. H₀: p = 0.5 H₁: p > 0.5 (b) Calculate the P-value. P-value = ☐ (Round to three decimal places as needed.)
