Using the t-distribution, it is found that the 95% confidence interval for the population mean rating for Miami is (5.73, 6.95).
<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 <u>two-tailed 95% confidence interval</u>, with 50 - 1 = <u>49 df</u>, is t = 2.0096.
Considering the given sample, the other parameters are given as follows:
Hence, the bounds of the interval are:

The 10th terms of given arithmetic sequence is -33
Further explanation:
The arithmetic sequence is a sequence where common difference is same for all consecutive terms.
An explicit formula is a general formula that is used to calculate terms of an arithmetic sequence directly.
Given
Here n is the term number
As we have to find the 10th term, we will put n=10
