ufacturer considers his production process to be out of control when defects exceed 4%. In a random sample of 146 items, the defect rate is 8.3% but the manager claims that this is only a sample fluctuation and production is not really out of control. At the 5% level of significance, use the p-value method to test the manager's claim. Enter the p-value. (Round your answer to nearest thousandth.) When using tables to find a tight range for the p-value, enter one of the boundaries of the interval (not 0 or 1) found using the tables.

In a recent year, the Better Business Bureau settled 73% of complaints they received. You have been hired by the Bureau to investigate complaints this year involving computer stores. You plan to select a random sample of complaints to estimate the proportion of complaints the Bureau is able to settle. Assume the population proportion of complaints settled for the computer stores is 0.73, as mentioned above. Suppose your sample size is 113. DO NOT USE THE EXCEL FORMULA. CALCULATE BY HAND OR WITH A CALCULATOR. 1. What is the probability that the sample proportion will be within 4 percent of the population proportion?

Twelve percent of the world's population is left-handed. A researcher claims that left-handed individuals are more creative than those who aren't left-handed. In order to support his claim, he takes a sample of 1650 artists and finds that 14% of.them are left-handed. Español Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p, where p is the proportion of left-handed individuals in a random sample of 1650. 00 (b) Find the standard deviation of p. (c) Compute an approximation for P (p s0.14), which is the probability that there will be 14% or fewer left-handed people in a random sample of 1650. Round your answer to four decimal places.
