- A law enforcement organization claims that their radargun is accurate to within 0.5 miles per hour for a courthearing. An independent organization hired to test theaccuracy of the radar gun conducted 12 tests on a projectilemoving at 60 miles per hour. Given the data inthe following table, determine if the radar gun can beused in court. State the hypothesis and base your commentson an appropriate α level.A local tennis pro-shop strings tennis rackets at the tension (pounds per square inch) requested by the customer. Recently a customer made a claim that the pro-shop consistently strings rackets at lower tensions, on average, than requested. To support this claim, the customer asked the pro shop to string 6 new rackets at 68 psi. Suppose the two-tailed P-value for the test described above (obtained from a computer printout) is 0.07 Give the proper conclusion for the test. Use a= 0.05A local tennis pro-shop strings tennis rackets at the tension (pounds per square inch) requested by the customer. Recently a customer made a claim that the pro-shop consistently strings rackets at lower tensions, on average, than requested. to support this claim, the customer asked the pro shop to string 6 new rackets at 68 psi. Suppose the two-tailed p-value for the test described above (obtained from a computer printout) is 0.07. Give the proper conclusion for the test. Use α = 0.05. a) There is sufficient evidence to conclude that μ, the true mean tension of the rackets, is less than 68 psi. b) There is insufficient evidence to conclude that μ, the true mean tension of the rackets, is less than 68 psi. c) Accept H0 and conclude that μ, the true mean tension of the rackets, equals 68 psi. d) Reject H0 and conclude that μ, the true mean tension of the rackets, equals 68 psi.
