Ilya [14]

The percent of the time Nicholas earned is the percent of the time 25%

The 5 values of the given box plot are;

The minimum fee = 20

In the first quartile, the 25th percentile point, Q₁ = 25

In the median or second quartile, the fiftieth percentile factor, Q₂ = 30

The 1/3 quartile, the 75th percentile point, Q₃ = 40

The maximum value = 55

The range = The most value - The minimal fee

The range = 55 - 20 = 35

We are aware that Nicholas earned $25 or less from the minimum value up to the first quartile, Q₁, which is the 25th percentile point, in which we've got 25 percent of the statistics points.

Consequently, the percentage of the time Nicholas earned $25 or much less is 25 percent of the time.

In mathematics, a percentage is a variety of ratios that can be expressed as a fraction of 100. If we have to calculate the percent of various, divide the wide variety by way of the whole and multiply by way of a hundred. For this reason, the shared approach is a component in line with a hundred. The phrase according to cent means in keeping with one hundred.

A relative cost indicates the hundredth component of any amount. One percent (symbolized 1%) is the hundredth part; for this reason, a hundred percent represents the whole lot and two hundred percent specifies two times the given amount.

Multiply the entire number amount through the decimal equal to the proportion. The end result is the share portion quantity. (consequently, this answers the question “How a whole lot is 24 percentage of 500,” you examine that 24 percent of 500 is a hundred and twenty).

shepuryov [24]

Answer:

Step-by-step explanation:

1) The null hypothesis is,

H_0: The mean thickness of teh wafers for the five positions are equal

i.e, $H_0:\mu_1=\mu_2=\mu_3=\mu_4=\mu_5$

2)

The alternative hypothesis is,

H_1: There is an evidence of a difference in the mean thickness of the wafers for the five positions

3)

Let us consider the level of significance $\alpha=0.01$

from the Minitab outout

One-way ANOVA:C1 versus C2

source DF SS MS F P

C2 4 1417.73 354.43 51.00 0.00

Error 145 1007.77 6.95

Total 14 2425.50

S = 2.636 R - S = 58.45% R - Sq(adj) = 57.31%

Individual 95% CIs For Mean Based on Pooled StDev

level N Mean StDev -,----------,----------,----------,----------

1 30 240.53 2.62 (--,--)

2 30 243.73 2.79 (--,--)

3 30 246.07 2.90 (--,--)

4 30 249.10 2.66 (--,--)

5 30 247.07 2.15 (--,--)

-,----------,----------,----------,----------

240.0 243.0 246.0 249.0

Pooled StDev = 2.64

4)

The test statistic is, F = 51

5)

The P-value is approximately 0

6)

Here, the P - value is less than the level of significance

$\therefore \,P-value$

So, we do not accept our null hypothesis H_0

7)

Therefore, we conclude that there is an evidence of a difference in the mean thickness of the wafers for the five positions at level of significance $\alpha=0.05$

b)

chek attachment

we observe that,

The mean thickness of the wafer for position 1 is significant with position 2,

position 18, position 19 and position 28.

The mean thickness of the wafer for position 2 is significant with position 18,

position 19 and position 28.

The mean thickness of the wafer for position 18 is significant with the

position 19.

But the mean thickness of the wafer for position18 is not significant with

position 28.

The mean thickness of the wafer for position 19 is significant with position 28.

Solve T=L(7 + RS) for S.<br> Please help

nikklg [1K]

multiply the ones in bracket by the L

T = 7× L + L × RS

T = 7L + LRS

making S the subject by transferring 7L to the left hand side of the equation.

thus

T - 7L = LRS

dividing through by LR

$\frac{T}{LR} - \frac{7L}{LR} = S$

$S= \frac{T}{LR} - \frac{7}{R}$
