looks like it could be D but the picture is kind of blurry
Using the t-distribution, as we have the standard deviation for the sample, it is found that the 95% confidence interval for the number of units students in their college are enrolled in is (11.7, 12.7).
<h3>What is a t-distribution confidence interval?</h3>
The confidence interval is:
In which:
- is the sample mean.
- s is the standard deviation for the sample.
The critical value, using a t-distribution calculator, for a two-tailed <em>95% confidence interval</em>, with 49 - 1 = <em>48 df</em>, is t = 2.0106.
Hence:
The 95% confidence interval for the number of units students in their college are enrolled in is (11.7, 12.7).

A. 254.55, you add all the numbers up to get 2800 and divide by 11
b. 254, when you order it from least to greatest the number in the middle is 254
c. 234 and 263, the are the most reoccurring numbers out of the others
d. 91, the greatest number 304 - 213 (the least number) is 91
the results wouldn’t represent ALL players in the sports league because everyone’s weight varies differently.
48 I think that’s the right one
