Test the claim about the population mean μ at the given level of significance using the given sample statistics. claim: μ ≠ 5000; α =0.06. sample statistics: x= 5100, s = 343, n = 50 identify the null and alternative hypotheses.

Null hypothesis =

Alternate hypothesis=  

We accept the null hypothesis

Step-by-step explanation:

Given : Claim: μ ≠ 5000; α =0.06. Sample statistics: x= 5100, s = 343, n = 50

To Find :test the claim about the population mean μ at the given level of significance using the given sample statistics. and identify the null and alternative hypotheses.

Solution:

Claim: μ ≠ 5000; α =0.06

So, Null hypothesis =

Alternate hypothesis=  

Sample statistics: x= 5100, s = 343, n = 50

Since n > 30

So, we will use z test

Substitute the values

refer the z value using z table

P(z) = 0.9803

So, p value is 0.9803

Since p value is greater than α

So, we accept the null hypothesis

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

50- 250 is correct i did that one too
