A survey is planned to compare salaries of plant managers in two regions. The plan is to take a sample of 200 plantmanagers from each region and ask their annual salaries. Assume that previous sample statistics suggest thato, = 0, = $4000. Are the sample sizes sufficient to produce a 95% confidence interval on H - H, having a width of%3Donly $1000?Click here to view page 1 of the standard normal distribution table.The sample sizesV sufficient because the samples would need to be at leastpeople each, which isthe planned sample sizes of 200.(Round up to the nearest whole number as needed.)

An agricultural researcher plants 14 plots with a new variety of corn. The average yield for these plots is X = 155 bushels per acre. Assume that the yield per acre for new variety of corn follows a normal distribution with unknown mean and a calculated sample standard deviation s = 10 bushels. A 90% confidence interval for the unknown mean is
