Which statement is correct?

kondor19780726 [428]

Answer:

Correct option is (a).

Step-by-step explanation:

The dependent t-test (also known as the paired t-test or matched-samples t-test) compares the two means associated groups to conclude if there is a statistically significant difference amid these two means.

We use the paired t-test if we have two measurements on the same item, person or thing. We should also use this test if we have two items that are being measured with a unique condition.

For instance, an experimenter tests the effect of a medicine on a group of patients before and after giving the doses.

Or in case of testing the level of reading comprehension of students before and after the speed-reading class we use t-test for dependent means.

The assumptions of paired t-test are:

The dependent variable that is tested should be continuous
The observations are independent

The dependent variable is normally distributed
There should not be any outliers.

Since the data consists of matched pair, both the samples must be of the same size.

Thus, the correct option is (a).

a father is 25 years older than his son.Five years ago he was 6 time old as his son was find their presents

IceJOKER [234]

Answer:

the present age of the father be x and the present age of the son be y.

It is given that man is 24 years older than his son that is:

x=y+24

x−y=24..........(1)

Also, 12 years ago, he was five times as old as his son that is:

(x−12)=5(y−12)

x−12=5y−60

x−5y=−60+12

x−5y=−48..........(2)

Now subtract equation 1 from equation 2 to eliminate x, because the coefficients of x are same. So, we get

(x−x)+(−5y+y)=−24−48

i.e. −4y=−72

i.e. y=18

Substituting this value of y in (1), we get

x−18=24

i.e. x=24+18=42

Hence, the present age of the father is 42 years and the present age of the son is 18 years.
