Question 3 A study was performed to determine whether men and women differ in their repeatability in assembling components on pr

Fed [463]

Answer:

There is no sufficient evidence to support the claim that men and women differ in repeatability for this assembly task

Step-by-step explanation:

Given

Let subscript 1 represent men and 2 represent women, respectively.

$n_1 = 25$

$n_2 = 21$

$s_1 = 0.98$

$s_2 = 1.02$

$\alpha = 0.02$

Required

Determine if here is enough evidence

First, we need to state the hypotheses

$H_o: \sigma_1^2 = \sigma_2^2$

$H_1: \sigma_1^2 \ne \sigma_2^2$

Next, calculate the test statistic using:

$F = \frac{s_1^2}{s_2^2}$

$F = \frac{0.98^2}{1.02^2}$

$F = 0.923$

Calculate the rejection region;

But first, calculate the degrees of freedom

$df_1 =n_1 - 1$

$df_1 =25 - 1$

$df_1 =24$

$df_2 = n_2 -1$

$df_2 = 21 - 1$

$df_2 = 20$

Using the F Distribution: table

$c = \frac{\alpha}{2}$

$c = \frac{0.02}{2}$

$c = 0.01$

At 0.01 level (check row 20 and column 24), the critical value is:

$f_{0.01,24,20} = 2.86$ --- the upper bound

At 0.01 level (check row 24 and column 20), the critical value is:

$f_{0.01,20,24} = 2.74$

Calculate the inverse F distribution.

$f_{0.99,20,24} = \frac{1}{f_{0.01,20,24}} = \frac{1}{2.74} =0.365$ ---- the lower bound

The rejection region is then represented as:

$0.365 < Test\ Statistic < 2.86$

If the test statistic falls within this region, then the null hypothesis is rejected

$F = 0.923$ --- Test Statistic

$0.365 < 0.923 < 2.86$

The above inequality is true; so, the null hypothesis is rejected.

This implies that, there is no sufficient evidence.

The sum of two consecutive integers is no more than 209. what is the larger of the two integers? enter your answer in the box.

puteri [66]

209÷2=104.5
104.5 is the number between the two consecutive integers, therefore the first number would be 104 and the other would be 105
104+105=209

The volume of dry goods like apple or peaches can be measured using bushels, pecks and quarts. A bushel contains 4 pecks and a p

Lisa [10]

Answer: $q= 32b$

Step-by-step explanation:

Given: A bushel contains 4 pecks and a peck contains 8 quarts.

i.e. A bush = 4 pecks

A peck = 8 quarts

Then, Number of quarts in 1 bush = 4 (8) =32

Let b = number of bushes and q = number of quarts

Number of quarts(q) in b bushes = 32b

hence, required equation: $q= 32b$ which describes the relationship between the number of b bushels and the number of q quarts.

Find the value of y if M is the midpoint of LN. 9y - 4 6y + 5 N help plz

AURORKA [14]

Answer:

If M is the midpoint, then LM = MN

3x - 2= 2x +1

x = 3

So LM = 3x - 2 = 9 -2 = 7

LM = 7
