Answer:

$\frac{11}{39}$

Step-by-step explanation:

There are 39 fruits in all.

$11 + 6 + 9 + 13= 39$

Therefore, there would be 39 total events.

There are 11 preferred events, as there are eleven oranges out of the 39 fruits.

$\frac{preferred}{total} =\frac{11}{39}$

So, there should be a 11/39 chance that a person would pick an orange.

$\frac{11}{39}$ is already in it's lowest terms.

Calculating the degrees of freedom, the sample variance, and the estimated standard error for evaluations using the t statistic

Yuliya22 [10]

Answer:

a) For the first part we have a sample of n =10 and we want to find the degrees of freedom, and we can use the following formula:

$df = n-1= 10-1=9$

d.9

b) $s^2 = \frac{SS}{n-1}= \frac{600}{41-1}= 15$

a.15

c) For this case we have the sample size n = 25 and the sample variance is $s^2 =400$ , the standard error can founded with this formula:

$SE = \frac{s^2}{\sqrt{n}}= \frac{400}{\sqrt{25}}= 80$

Step-by-step explanation:

Part a

For the first part we have a sample of n =10 and we want to find the degrees of freedom, and we can use the following formula:

$df = n-1= 10-1=9$

d.9

Part b

From a sample we know that n=41 and SS= 600, where SS represent the sum of quares given by:

$SS = \sum_{i=1}^n (X_i -\bar X)^2$

And the sample variance for this case can be calculated from this formula:

$s^2 = \frac{SS}{n-1}= \frac{600}{41-1}= 15$

a.15

Part c

For this case we have the sample size n = 25 and the sample variance is $s^2 =400$ , the standard error can founded with this formula:

$SE = \frac{s^2}{\sqrt{n}}= \frac{400}{\sqrt{25}}= 80$

A cat spends about 7 out of 10 hours sleeping about what percent of a cat's day is spent sleeping

hram777 [196]

I understand that it means that out of every 10 hours, a cat spends 7 sleeping (not 7 hours in a day).

this means that a cat is sleeping $\frac{7}{10}*100%=70%$

a percentage stays constant, this means that a cat sleeps 70 % of each 10 hours, but also 70% of the day.
