A university researcher wants to estimate the mean number of novels that seniors read during their time in college. An exit survey was conducted with a random sample of 9 seniors. The sample mean was 7 novels with standard deviation 2.29 novels. Assuming that all conditions for conducting inference have been met, what is a 95 percent confidence interval for the population mean number of novels read by all seniors?

Answers

Answer:

(5.240 ; 8.760)

Step-by-step explanation:

Given :

Sample mean, xbar = 7

Standard deviation, s = 2.29

Sample size, n = 9

95% confidence interval for the population mean :

Confidence interval :

Xbar ± Margin of error

Margin of Error = Tcritical * s/sqrt(n)

Tcritical at 0.05 ; df = 8 = 2.306

Margin of Error = 2.306 * 2.29/sqrt(9)

Margin of Error = 1.760

Lower boundary = (7 - 1.760) = 5.240

Upper boundary = (7 + 1.760) = 8.760

(5.240 ; 8.760)

There were twelve times more children than adults at the matinee performance of the school play. There were 455 people at the play. How many adults and children were there?

Answers

Answer:

35 adults, 420 children

Step-by-step explanation:

1. Set up variables

Let's say children is c and adults is a.

2. Create the equations

c = 12a AND c + a = 455

3. Plug in the variables

Let's take c = 12a and substitute it in for c in the equation "c + a = 455." That would be...

12a + a = 455

13a = 455

a = 35

3. Plug in more variables

Now we have our answer for a, so let's plug it into the other equation. That would be...

c + a = 455

c + 35 = 455

c = 420

The parent function f(x) = log3x has been transformed by reflecting it over the x-axis, stretching it vertically by a factor of two and shifting it down three units. which function is representative of this transformation?

g(x) = log3(-2x) - 3
g(x) = -2log3(x) - 3
g(x) = 2log3(x) + 3
g(x) = log3(2x) + 3

Answers

Answer:

f(x) =  -2 log3x - 3.

Step-by-step explanation:

f(x) = log3x

Reflecting over x axis makes it  f(x) = f(x) = -log3x

Vertical stretch gives -2 log3x

Finally moving the graph down 3 units gives  -2 log3x - 3.

An orange traffic cone has a diameter of 14 inches and a height of 28 inches. What is the volume of the traffic cone? Round to the nearest tenth.

Answers

Answer:

14367 inch^3

Step-by-step explanation:

Diameter of the cone= 14 inches

Radius of the cone= Diameter/2= 14/2= 7 inches

Height= 28 inches.

Volume of the cone = 1/3 π r^2 .h

Then substitute for the values, we have

Volume= 1/3 × π × 7^2 × 28

Volume= 1436.9 inch^3

Volume in nearest tenth= 14367 inch^3

A university is applying classification methods in order to identify alumni who may be interested in donating money. The university has a database of 58,205 alumni profiles containing numerous variables. Of these 58,205 alumni, only 576 have donated in the past. The university has oversampled the data and trained a random forest of 100 classification trees. For a cutoff value of 0.5, the following confusion matrix summarizes the performance of the random forest on a validation set:
Predicted
Actual No Donation Donation
Donation 268 20
No Donation 5375 23439
The following table lists some information on individual observations from the validation set:

Observation ID Actual Class Probability of Donation Predicted Class
A Donation 0.8 No Donation
B No Donation 0.1 Donation
C No Donation 0.6 Donation
Compute the values of accuracy, sensitivity, specificity, and precision.

Answers

Answer:

Accuracy = 0.81

Sensitivity = 0.93

Specificity = 0.81

Precision = 0.047

Step-by-step explanation:

Given the confusion matrix :

Actual_______ Donation___ No Donation

Donation______ 268 (TP) _______ 20 (FN)

No Donation ___5375 (FP) _____23439 (TN)

Accuracy is calculated as :

(TP + TN) / (TP+TN+FP+FN)

(268 + 23439) / (268 + 23439 + 5375 + 20)

ACCURACY = (23707 / 29102) = 0.81

Sensitivity (True positive rate) :

TP ÷ (TP + FN)

268 ÷ (268 + 20)

268 ÷ 288 = 0.93

Specificity (True Negative rate) :

TN ÷ (TN + FP)

23439 ÷ (23439 + 5375)

23439 ÷ 28814

= 0.81

Precision :

TP ÷ (TP + FP)

268 ÷ (268 + 5375)

268 ÷ 5643

= 0.047

Landon has a points card for a movie theater. He receives 70 rewards points just for signing up. He earns 5.5 points for each visit to the movie theater. He needs 125 points for a free movie ticket. How many visits must Landon make to earn a free movie ticket?

Answers

Answer:

10 times

Step-by-step explanation:

125-70 bonus points =55 points left.

55 divided by 5.5 per visit = 10 times to get a free movie ticket.

To verify it is correct:

10 visits x 5.5 points each = 55 points total

55 + 70 bonus points = 125 for a free ticket.

Answer:

10

Step-by-step explanation:

Let x= number of visits

5.5x+70=

125

subtract -70 from 70 and 125

5.5x=  55

divide both sides by 5.5

x=10

What is the measure of Arc BA? An explanation would be much appreciated.

Answers

Answer:

m<BA = 180degrees

Step-by-step explanation:

First you must know that measure of <BA is 180 degrees and m<CD = m<BA

Since <CD = 16z - 12, hence;

180 = 16z - 12

16z = 180++12

16z = 192

z = 192/16

z = 12

Get <BA

m<BA = 16z - 12

m<BA = 16(12) - 12

m<BA = 192 - 12

m<BA = 180degrees
