The mean hourly wage for employees in goods-producing industries is currently $24.57 (Bureau of Labor Statistics website, April, 12, 2012). Suppose we take a sample of employees from the manufacturing industry to see if the mean hourly wage differs from the reported mean of $24.57 for the goods-producing industries a. State the null hypotheses we should use to test whether the population mean hourly wage in the manufacturing industry differs from the population mean hourly wage in the goods-producing industries 1. Ho: μ-2457 2. Ho: μ * 24.57 3. Ho: i > 24.57 Choose correct answer from above choice State the alternative hypotheses we should use to test whether the population mean hourly wage in the manufacturing industry differs from the population mean hourly wage in the goods-producing industries. 1. Hi μ+24.57 2. Η μ-2457 3. Hi u >24.57 Choose correct answer from above choice b. Suppose a sample of 30 employees from the manufacturing industry showed a sample mean of $23.89 per hour. Assume a population standard deviation of $2.40 per hour and compute the p-value. Round your answer to four decimal places 0.1192 c. with α-.05 as the level of significance, what is your conclusion? p-value05, onot reject Ho. We cannot concludethat the population mean hourly wage for manufacturing workers differs significantly fromthe population mean of $24.57 for the goods-producing industries .05, do not reject A|OH o. We cannot concludethat the population mean hourly wage for manufacturing workers differs significantly fromthe population mean of $24.57 for the goods-producing d. Repeat the preceding hypothesis test using the critical value approach. Round your answer to two decimal places. Enter negative values as negative numbers cannot reject

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
