Answer:

Step-by-step explanation:

Let "a number" = x

4(x - 4) = 24

Isolate the x. First, divide 4 from both sides

(4(x -4))/4 = (24)/4

x - 4 = 6

Add 4 to both sides

x - 4 (+4) = 6 (+4)

x = 6 + 4

x = 10

10 is your answer for "a number"

A machine used for packaging seedless golden raisins is set so that their standard deviation in the weight of raisins packaged p

Kazeer [188]

Answer:

population standard deviation does not differ from 0.25

Step-by-step explanation:

The hypothesis :

σ² = 0.25²

σ² ≠ 0.25²

The Chisquare statistic, χ²: (n-1)*s²/σ²

Where s² = sample variance ; sample size, n = 30

Using calculator, the sample variance, s² = 0.1646

χ² = (n-1)*s²/σ²

χ²: (30 - 1) * 0.1646 / 0.25²

χ² = (29 * 0.1646) / 0.0625

χ² = 0.3292 / 0.0625

χ² = 5.2672

α = 0.05

Using the Pvalue from Chisquare calculator ; df = 29

Pvalue = 1

Since, Pvalue > α ; We fail to reject the null and conclude that population standard deviation does not differ from 0.25
