One sample has Aa Aa One sample has n 10 scores and a variance of s2 20, and a second sample has n 15 scores and a variance of s

siniylev [52]

Answer:

option (a) It will be closer to 30 than to 20

Step-by-step explanation:

Data provided in the question:

For sample 1:

n₁ = 10

variance, s₁² = 20

For sample 2:

n₂ = 15

variance, s₂² = 30

Now,

The pooled variance is calculated using the formula,

$S^{2}_{p} = \frac{(n_{1}-1)\times s^{2}_{1} +(n_{2}-1)\times s^{2}_{2}}{n_{1}+n_{2}-2}$

on substituting the given respective values, we get

$S^{2}_{p} = \frac{(10-1)\times 20 +(15-1)\times 30}{10+15-2}$

$S^{2}_{p}$ = 26.0869

Hence,

the pooled variance will be closer to 30 than to 20

Therefore,

The correct answer is option (a) It will be closer to 30 than to 20

Varvara68 [4.7K]

Answer:

$\frac{6}{8}$ or $\frac{3}{4}$

Step-by-step explanation:

Convert the mixed numbers into improper fractions.

$2\frac{3}{8}-1\frac{5}{8}=\frac{19}{8}-\frac{13}{8}$

Since the two fractions have the same denominator, just subtract the numerators.

$\frac{19}{8}-\frac{13}{8}=\frac{6}{8}$

If required, rewrite the fraction in simplest form.

$\frac{6}{8}=\frac{3}{4}$
