Suppose Julio is a veterinarian who is doing research into the weight of domestic cats in his city. He collects information on 1

Answer:

Estimate of the standard error of the mean = 0.38 lb

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ = 10.87 lb

Sample size, n = 131

Standard deviation, σ = 4.31 lb

We have ti find the estimate of the standard error of the mean.

Formula for standard error:

$S.E= \dfrac{\sigma}{\sqrt{n}}$

Putting values, we get,

$S.E = \dfrac{4.31}{\sqrt{131}} = 0.3766 \approx 0.38$

0.38 lb is the standard error of the mean.

A university is applying classification methods in order to identify alumni who may be interested in donating money. The univers

HACTEHA [7]

The accuracy in the research done by university is 0.81, sensitivity is 0.93, specificity is 0.81 and precision is 0.047.

Given sample size of 58205 and proportion of people donated 576. Cutoff is 0.5.

Probability is the chance of happening an event among all the events possible. It lies between 0 and 1.

TP=total people donated in sample, TN=total number of people,FP=donation,FN=No donation

Accuracy is calculated as under:

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

=(268+23439)/(238+23439+5375+20)

=23707/29102

=0.81

Accuracy=0.81

Sensitivity is calculated as under:

=TP/(TP+FN)

=268/(268+20)

=268/288

=0.93

Precision is calculated as under:

=TP/(TP+FP)

=268/(268+5375)

=268/5643

=0.047

Their values are the probabilities in itself.

Hence accuracy is 0.81, sensitivity is 0.93, specificity is 0.81 and precision is 0.047.

Please tell me the answer ASAP Lynette's average score on five tests is 18. If she scores 24 points on her sixth test, what is h

Helga [31]

Answer:

The average score of 6 tests is 19.

Step-by-step explanation:

Given that the average score of 5 tests is 18. So first, we have to find the total number of scores for 5 tests :

$let \: x = total \: no. \: of \: scores$

$\frac{x}{5} = 18$

$x = 18 \times 5$

$x = 90$

We have found out that the total scores for 5 tests is 90. So we have to find the average of 6 scores :

$\frac{x + 24}{5 + 1} = \frac{90 + 24}{6} = \frac{114}{6} = 19$
