Answer: Sometimes
Explanation:
Quotient greater than 1:
3/4 divide by 2/3
= 3/4 x 3/2 = 9/8 > 1
4/5 divide by 2/5
= 4/5 x 5/2 = 2 > 1
Quotient less than 1
1/100 divide by 2/10
= 1/100 x 10/2 = 1/20 < 1
1/50 divide by 1/25
= 1/50 x 25/1 = 1/2 < 1
Answer:
And the 96% confidence is given by (110.06; 117.34)
Step-by-step explanation:
Information given
represent the sample mean
population mean (variable of interest)
s=9.1 represent the sample standard deviation
n=29 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom are given by:
The Confidence is 0.96 or 96%, the significance is and , and the critical value would be
Replacing the info we got:
And the 96% confidence is given by (110.06; 117.34)
