The idea for transitions for an equation like this is
where m = slope
h = how much left or right (note the negative)
k = how much up or down
moving 13 down would mean
k = -13
so
D. would be your answer

Using the t-distribution, the 90% confidence interval for the mean number of absences is given by: (9.22, 11.60).
<h3>What is a t-distribution confidence interval?</h3>The confidence interval is:
In which:
is the sample mean.
- t is the critical value.
- n is the sample size.
- s is the standard deviation for the sample.
The critical value, using a t-distribution calculator, for a two-tailed 90% confidence interval, with 28 - 1 = 27 df, is t = 1.7033.
Researching this problem on the internet, the parameters are given by:
.
Hence the bounds of the interval are given by:
The 90% confidence interval for the mean number of absences is given by: (9.22, 11.60).
