Test H0 that the population mean wage rate is $32/hr, at a 5% significance level. Would you be correct to say, “There is sufficient evidence to conclude that the population mean wage rate is below $32/hr?” Explain why or why not.

Stuck and confused

PLEASE HELP! stressed is and understatement!please show your work and if possible please write neatly. i will use your help as a study guide to practice and until I fully understand.

How do I find the standard deviation

What is true or false of this questions?

(a) Formulate a probability statement to determine the value of z so that the area under the standard normal curve in the right tail is 0.0330: P(Za) 0.0330 (b) Convert the probability statement relating to an area to the left of the normal curve: (c) Locate the closest probability value available in the standard normal table. Give the answer with four decimal places. The closest probability value i (d) Find the z value corresponding to the answer for (c). Give the answer with two decimal places. Z= P(Zsa)-0.967

need answer and explanation

Question TU A population of values has a distribution with u = 52.4 and o = 77.8. You intend to draw a random sample of size n = 39. According to the Central Limit Theorem: (a) What is the mean of the distribution of sample means? = (b) What is the standard deviation of the distribution of sample means? (Report answer accurate to 4 decimal place.) (C) In a random sample of n=39, what is the probability that its sample mean is more than 55.1? Round to three decimal places. (d) In a random sample of n=39, what is the probability that its sample mean is less than 53.7? Give your answer to three decimal places. > Next Question
