Can you answer these questions:

Question 1.

Suppose that the Giant Springs Water Co. is bottling 12oz. bottles of water and claim that their standard deviation is less than half an ounce per bottle. If they sample 24 bottles and find the sample standard deviation is 0.54 oz is there claim correct at=0.005=0.005

What type of test should be used?

z-test for the mean

t-test for the mean

z-test for the mean

2 test for the standard deviation

Question 2:

Suppose that the Giant Springs Water Co. is bottling 12oz. bottles of water and claim that their standard deviation is less than half an ounce per bottle. If they sample 24 bottles and find the sample standard deviation is 0.54 oz is there claim correct at =0.005=0.005

What is the claim?

Question 2 options:

a. =0.5=0.5

b.0.50.5

c.0.50.5

d.0.50.5

e.<0.5<0.5

f. >0.5

Question 3:

Suppose that the Giant Springs Water Co. is bottling 12oz. bottles of water and claim that their standard deviation is less than half an ounce per bottle. If they sample 24 bottles and find the sample standard deviation is 0.54 oz is there claim correct at =0.005=0.005

Determine the null and alternate hypothesis.

Question 3 options:

H0:0.5H1:<0.5

H0:=0.5H1:0.5

H0:0.5H1:>0.5

Question 4:

Suppose that the Giant Springs Water Co. is bottling 12oz. bottles of water and claim that their standard deviation is less than half an ounce per bottle. If they sample 24 bottles and find the sample standard deviation is 0.54 oz is there claim correct at=0.005.

Determine the test value. (round to 3 decimal places)
