What is absolute deviation?

1 answer:

7 0

The average absolute deviation (or mean absolute deviation ( MAD )) about any certain point (or 'avg. absolute deviation' only) of a data set is the average of the absolute deviations or the positive difference of the given data and that certain value (generally central values). answer:

When multiplying and/or dividing fractions, answer if each of the statements below are TRUE or FALSE.

1. Only true to division. Most likely though when multiplying it's more helpful to have the denominators the same.

2. True

3. False

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.

PLZZ HELPP!!

There's one piece of information missing from the question, so
in order to completely calculate the answer, we must assume the
missing number.

We have no information that helps us calculate the probability
that you will eat the first jelly bean. So we'll have to assume that
you will definitely eat it, no matter what color it is. The probability is 1 .

-- You start out with (2 + 4 + 8 + 6) = 20 jelly beans in the package.
    8 of them are purple.

-- If you close your eyes and pull one out of the package, then the
probability that it will be purple is
      8 / 20 .

-- You definitely eat it. The probability of this event is 1 .

-- Now there are 19 jelly beans left in the package.
   6 of them are blue.

-- The probability of picking a blue one out of the package without peaking is

   6 / 19 .

-- The probability of all three of these events happening is

   (8/20) · (1) · (6/19)

   = (8 · 1 · 6) / (20 ·19)

   =    48 / 380

   = 12/95 = 0.1263... = 12.63...% (rounded)
