Consider the following hypothesis test: h0 : μ ≤ 38 ha : μ > 38 you are given the following information obtained from a random sample of six observations. x 38 40 42 32 46 42
(a) using = 0.05, what is the rejection rule?
(b) determine the standard error of the mean.
(c) compute the value of the test statistic. what is your conclusion?

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

x = -2

y = 848
