At many golf​ clubs, a teaching professional provides a free​ 10-minute lesson to new customers. A golf magazine reports that go

lf facilities that provide these free lessons​ gain, on​ average, ​$2 comma 100 in green​ fees, lessons, or equipment expenditures. A teaching professional believes that the average gain exceeds ​$2 comma 100. Complete parts a through c below. a. In order to support the claim made by the teaching​ professional, what null and alternative hypotheses should you​ test? Upper H 0​: mu equals ​$2 comma 100 Upper H Subscript a​: mu greater than ​$2 comma 100 b. Suppose you select alphaequals0.01. Interpret this value in the words of the problem. The probablility that the null hypothesis is ▼ when the average gain ▼ is is not is less than exceeds ​$2 comma 100 is 0.01. c. For alphaequals0.01​, specify the rejection region of a​ large-sample test. Choose the correct answer below.

Answer:

Step-by-step explanation:

a) The objective of the study is test the claim that the average gain in the green fees , lessons or equipment expenditure for participating golf facilities is less than $2,100 under the claim the null and alternative hypothesis are,

H₀ : μ = $2,100

H₀ : μ < $2,100

B) Suppose you selects α = 0.01

The probability that the null hypothesis is rejected when the average gain is $2,100 is 0.01

C) For α = 0.01

specify the rejection region of a large sample test

At the given level of significance 0.01 and the test is left-tailed then rejection level of a large-sample = < - 1.28

Solve for y z= x+y/5 due in 9 mins
Makovka662 [10]

Answer:

y = 5z - x

Step-by-step explanation:

Given

z = \frac{x+y}{5} ( multiply both sides by 5 to clear the fraction )

5z = x + y ( subtract x from both sides )

5z - x = y

A rectangular prism has a height of 4 meters, a surface area of 96 square meters, and a base area of 8 square meters. Calculate
tatyana61 [14]
The perimeter is 56m

H = 4m
Base area =  96m^2

96/4 = 24
Therefore the length is 24m

4m + 24 = 28m
multiplied by 2 is equal to 56m.

What is 2.23 as a fraction
Bezzdna [24]
2.23 as a fraction would be 2 and 23/100. Since the "3" is in the hundred<em>th</em>s place, the fraction has to be over 100. The 2 in front of the decimal point (.) is the whole number. That means 2.23 as a fraction would be 2 and 23/100.
