. If the researcher had used an ANOVA to evaluate the data, what F-ratio would be obtained?
a. F(1, 11) = 2.00
b. F(1, 12) = 16.00
c. F(1, 12) = 2.00
d. F(1, 11) = 16.00

Answer:

B). F(1, 12) = 16.00

Step-by-step explanation:

'ANOVA' is a measure employed for 'analysis of a variance' in a given set of data of treatments or populations. While t-test helps in comparing their means.

As per the question, the F-ratio using ANOVA would be 'F(1, 12) = 16.00.' In order to calculate the variances, the distinction among the samples. The б^2 denotes the difference of representative means which is augmented by n(in case of samples being same). So, the ratio of F(1, 12) would be б^2 i.e. 4^2 = 16 since the sample sizes are distinct. Thus, <u>option B</u> is the correct answer.

USPshnik [31]

Answer:

$204

Step-by-step explanation:

The question is at what price x will the company maximize revenue.

The revenue function is:

R(x) = 4,080x-10x^2

The price for which the derivate of the revenue function is zero is the price the maximizes revenue:

R(x) = 4,080x-10x^2\\\frac{dR(x)}{dx}=0=4,080-20x\\x=\frac{4,080}{20}\\ x=\$204

The company will maximize its revenue when the price is $204.

Answer:

20%

Step-by-step explanation:

Step 1: Subtract starting value minus the final value (decrease)

\$5.75 - \$4.60\\\\= 5.75 - 4.60 \\\\= 1.15

Step 2: Divide the decrease by the original number

1.15 \div 5.75\\\\= \frac{1.15}{5.75}\\\\= 0.2

Step 3: Multiply the result by 100 to get a percent decrease

0.2 \times 100\\\\= 20

Therefore, the percent decrease of the price of paper per package is 20%

<em>Note: If the percentage is negative, it means there was an increase and not a decrease.</em>
