Complete Question:
The mean hourly wage for employees in goods-producing industries is currently $24.57 (Bureau of Labor Statistics website, April, 1 2, 201 2). 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. State the null and 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
Answer:
Null hypothesis, H₀ : μ = 24.57
Alternative hypothesis, : μ ≠ 24.57
Step-by-step explanation:
The mean hourly wage for the goods producing industry = $24.57
Since we want to see if the mean of hourly wage for the manufacturing industry is equal to $24.57( The mean f hourly wage for the good producing industry)
Therefore the, null hypothesis will be that there is no significant difference between the means of the hourly wages of both the goods producing and the manufacturing industries, while the alternative hypothesis will be that the means of their hourly wages are significantly different
Null hypothesis, H₀ : μ = 24.57
Alternative hypothesis, : μ ≠ 24.57
Answer: a. 0.04
Step-by-step explanation:
Given : Number of multiple choice questions = 2
Choices given in each question = 5
Since only one choice is correct out of 5.
So, the probability of selecting the correct answer =
Also, both questions are independent of each other.
It means , The probability of answering the two multiple choice questions correctly if random guesses are made
=( Probability of selecting the correct answer in question 1 ) x ( Probability of selecting the correct answer in question 2 )
=
Hence, the required probability =0.04
