The number of successes and the sample size for a simple random sample from a population are given. a. Determine the sample proportion. b. Decide whether using the one-proportion z-interval procedure is appropriate. c. If appropriate, use the one-proportion z-interval procedure to find the confidence interval at the specified confidence level. x= 175, n= 250, 90% level a. What is the sample proportion?The number of successes and the sample size for a simple random sample from a population are given. a. Determine the sample proportion. b. Decide whether using the one-proportion z-interval procedure is appropriate. c.
