Answer:
three terms
Step-by-step explanation:
3x + 2y + 8z
Since we cannot simplify
There are three terms
3x, 2y, 8z
The ratio, r, is 20 - 13 = 27 - 20 = 34 - 27 = 7;
The nth term has the formula: an = a1 + (n-1) x r; where, a1 = 13 and r = 7;
Then, an = 13 + (n-1) x 7;
Finally, an = 13 + 7 x n - 7;
an = 7 x n + 6;
Answer: Reject if the confidence interval <u>does not</u> contain the value of the hypothesized mean .
Step-by-step explanation:
In the case of Confidence Intervals and Two-Tailed Hypothesis Tests,
Null hypothesis : [There is no change in mean.]
Alternative hypothesis: [There is some difference.]
Since confidence intervals contain the true population parameter ( mean).
So, Decision rule states that
- Reject if the confidence interval <u>does not </u>contain the value of the hypothesized mean .
- We do not reject if the confidence interval contains the value of the hypothesized mean .
