Answer:
37
Step-by-step explanation:
Margin of error = critical value × standard error
For 98% confidence, CV = 2.326 (from t table).
Standard error is σ / √n, where σ is the population standard deviation, and n is the sample size.
Plugging in:
5 = 2.326 × 13 / √n
n = 36.6
Rounding up, n = 37.
Slope of f(x)
Slope of g(x)
PART A)
The slopes of f(x) and g(x) are the same.
PART B)
The equation for line f(x)
y = 4x + b
-1 = 4(0) + b
-1 = b
y = 4x - 1
The function G(x) has a bigger y-intercept. The y-intercept of g(x) is 3, while the y-intercept of f(x) is -1.

i simplified it but its not simple i dont know the answer so i cant help you
Answer: Ron's z-score is <u>+1.2</u>.
B. 1.2 standard deviation above the mean .
Step-by-step explanation:
Let X deontes the scores of the final exam
Given : Ms. Meyer's statistics class follow a normal distribution with Mean = 82
standard deviation =5.1
Formula : 
Ron scored 88 on the final.
So, put x=88

Ron's z-score is <u>+1.2</u>.
Also, 88= 86+(1.2 x 5.1) = Mean +1.2 x (standard deviation)
i.e. This means that Ron's final score is<u> 1.2 standard deviation above the mean </u>.
