The number of successes and the sample size for a simple random sample from a population are given below. x = 9, n = 36, H₁: p=0.4, H₂: p‡0.4, α = 0.05 a. Determine the sample proportion. b. Decide whether using the one-proportion z-test is appropriate. c. If appropriate, use the one-proportion z-test to perform the specified hypothesis test. Click here to view a table of areas under the standard normal curve for negative values of z. Click here to view a table of areas under the standard normal curve for positive values of z. a. The sample proportion is. (Type an integer or a decimal. Do not round.)
