I have tried this problem multiple times now and don't get the correct answer. Please help!

Vikentia [17]

The confidence interval is (-1.1059, 7.70459).

<h3>What is confidence interval in statistics?</h3>

Image result for what is confidence interval

A confidence interval is the mean of your estimate plus and minus the variation in that estimate.

The sample mean is M=3.3

The sample size is N=44

So, σM= s/√N = 16.6/ √44

= 16.6/ 6.633

= 2.621

and, the degree of freedom

df= n-1

=44-1

=43

So, The t-value for a 90% confidence interval and 43 degrees of freedom is t=1.681.

Now, Margin of error = 2.261* 1.681 = 4.4059

Now, the lower and upper bound of the confidence interval are:

LL = 3.3- 4.40459 = -1.1059

UL = 3.3+ 4.40459 = 7.70459

Hence, the confidence interval is (-1.1059, 7.70459).

an astronomer wishes to measure on a photograph the distance between the image of a certain star and three star other star image

Greeley [361]

The astronomer has to choose 3 star images out of 8.This is a problem of combinations. This can be expressed as 8C3 i.e. combination of 8 objects taken 3 at a time.

$8C3= \frac{8!}{3!*5!}=56$

This means, if 8 images are nearby the astronomer will have 56 choices <span>of the three stars.</span>
