A grocer has 36 apples and 20 pears. The grocer arranges the fruit into groups that have the same ratio of apples to pears as th

cupoosta [38]

Answer:

Therefore no of apples in that group is 18

Step-by-step explanation:

Given:

No. of apples = 36

No. of pears = 20

Also it is given that grocer arranges the fruit into groups that have the same ratio of apples to pears as the whole collection of fruit.

first we find the ratio of apples and pears in whole collection which is given below

No. of apples/No. of pears = 36/20 = 9/5

Now its a problem of ratio

It is given that no of pear in one group is 10

Let the no of apples in that group be X

According to the question

No. of apples in whole collection/ No. of pear in whole collection = No. of apples in the group/ No. of pears in the group -------------> A

9/5 =X/10

=> X = (9*10)/5 = 18

Therefore no of apples in that group is 18.

Ber [7]

Answer:

When sample size increases from n = 23 to n = 35, the mean of the distribution of sample means remains same but the standard deviation of the distribution of sample means decreases from 0.073 to 0.059.

Step-by-step explanation:

We are given the amounts of time employees at a large corporation work each day are normally distributed, with a mean of 7.5 hours and a standard deviation of 0.35 hour.

Random samples of size 23 and 35 are drawn from the population and the mean of each sample is determined.

Here, $\mu$ = population mean = 7.5 hours

$\sigma$ = population standard deviation = 0.35 hour

Let $\bar X$ = sample mean

(a) The random samples of size of n = 23 is drawn from the population;

So, mean of the distribution of sample means = $\mu$ = 7.5 hours

Standard deviation for the distribution of sample means is given by;

s = $\frac{\sigma}{\sqrt{n} }$ = $\frac{0.35}{23}$ = 0.073

(b) The random samples of size of n = 35 is drawn from the population;

So, mean of the distribution of sample means = $\mu$ = 7.5 hours

Standard deviation for the distribution of sample means is given by;

s = $\frac{\sigma}{\sqrt{n} }$ = $} \frac{0.35}{\sqrt{35} }$ = 0.059

(c) So, as we can see that when sample size increases from n = 23 to n = 35, the mean of the distribution of sample means remains same but the standard deviation of the distribution of sample means decreases from 0.073 to 0.059.
