If testing the claim that sigma subscript 1 superscript 2 baseline not equals sigma subscript 2 superscript 2σ21≠σ22, what do w

12345 [234]

Answer:

The statistic for this system of hypothesis is given by:

$F=\frac{s^2_1}{s^2_2}$

If the statistic is equal to 1 then that means $s^2_1 = s^2_2$ and we don't have enough evidence to conclude that the two population variances and deviations are different.

Step-by-step explanation:

System of hypothesis

We want to test if the variation for a group1 is equal to another one 2, so the system of hypothesis are:

H0: $\sigma^2_1 = \sigma^2_2$

H1: $\sigma^2_1 \neq \sigma^2_2$

Calculate the statistic

The statistic for this system of hypothesis is given by:

$F=\frac{s^2_1}{s^2_2}$

If the statistic is equal to 1 then that means $s^2_1 = s^2_2$ and we don't have enough evidence to conclude that the two population variances and deviations are different.

Tim has two spinners , spinnerA and spinner B. Each spinner can only land on red or blue . The probability that spinner A will l

Ganezh [65]

Answer:

Step-by-step explanation:

Spinner A

Probability of red = 0.5,
Probability of blue = 0.5

Spinner B

Probability of red = 0.6,
Probability of blue = 0.4

Probability of both A and B land on red:

0.5*0.6= 0.3

Number of attempts to get outcome of 84 red on both spinners is:

84/0.3= 260

Probability of both spinners land on blue:

0.5*0.4= 0.2

Estimated number of both spinners land on blue:

260*0.2= 52
