and its proof
Answer:
Correct option is (a).
Step-by-step explanation:
The dependent <em>t</em>-test (also known as the paired <em>t</em>-test or matched-samples <em>t</em>-test) compares the two means associated groups to conclude if there is a statistically significant difference amid these two means.
We use the paired <em>t</em>-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 <em>t</em>-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).
The total numbers of sections are 16.
Step-by-step explanation:
Given:
Number of boys in school = 576
Number of girls in school = 448
To find: Total Number of sections such that each section has either boys or girls.
Height Common Factor ( HCF ) of both number gives the number of students in a section.
HCF of 576 and 448
576 = 2 × 2 × 2 × 2 × 2 × 2 × 3 × 3
448 = 2 × 2 × 2 × 2 × 2 × 2 × 7
HCF = 2 × 2 × 2 × 2 × 2 × 2 = 64
Number of sections of Boys = 576/64 = 9
Number of sections of girls 448/64 = 7
Total Number of sections = 9 + 7 = 16
Therefore, The total numbers of sections are 16.
