The point estimate of difference of the sample his will be -20.
<h3>How to illustrate the information?</h3>
Based on the information given, the. following can be depicted:
n1 = 13
x1 = 141
s1 = 13
n2 = 9
x2 = 161
s2 = 12
The point estimate of difference will be:
= 141 - 161
= -20
The margin of error to be used in constructing the confidence interval will be calculated by multiplying the standard error which is 5.467 and the critical value. This will be:
= 5.467 × 2.528
= 13.822
The margin of error is 13.822.
The confidence interval will now be:
= (-20 + 13.822) and (-20 - 13.822)
= -6.178 and -33.822

Answer:
3/8
Step-by-step explanation:
Find the common factor, which is 24. To make the other fractions have a denominator of 24, multiply the denominator and numerator by a factor that will have the denominator get 24 (the multiplied number has to be the same for the top and bottom). 27/24 divided by 3 is 27/24.You will get 1/4=6/24, and 5/6=20/24. 6/24 + 20/24 = 26/24 + 1/24= 27/24. Divide by 3 since there are 3 numbers. Once you are done dividing, you will get 27/72, and 3/8 is the simplified answer.
