A survey is being planned to determine the mean amount of time corporation executives watch television. a pilot survey indicated
Natali [406]
Missing question: How many executives should be surveyed?

Solution:
Mean = 13 hours
SD = 3 hours
Confidence level = 95%

Mean viewing time within a quarter of an hour = 0.25 = 1.96*3/sqrt (N)

Where N = Sample population

N = {(1.96*3)/0.25}^2 = 553.19 ≈ 554

Therefore, 554 executives should be surveyed to yield such results.

Determine the value of f(2) that will lead to an average rate of change of 15 over the interval [2,6]. (HELP PLEASE)
Fofino [41]
  • Average Rate of Change/Slope Formula: \frac{y_2-y_1}{x_2-x_1}

So using points (6,71) and (2,y), and the slope of 15, plug them into the slope formula as such:

\frac{71-y}{6-2}=15

From here we can solve for y. Firstly, solve the subtraction:

\frac{71-y}{4}=15

Next, multiply both sides by 4:

71-y=60

Next, subtact both sides by 71:

-y=-11

Lastly, multiply both sides by -1, and <u>your final answer will be y=11 , or A.</u>
