A textile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 ki

MakcuM [25]

Answer:

P-value = 0.02275

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 12 kilograms

Sample mean, $\bar{x}$ = 11.5 kilograms

Sample size, n = 4

Alpha, α = 0.05

Population standard deviation, σ = 0.5 kilograms

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 12\\H_A: \mu < 12$

We use one-tailed(left) z test to perform this hypothesis.

Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$z_{stat} = \displaystyle\frac{11.5 - 12}{\frac{0.5}{\sqrt{4}} } = -2$

We calculate the p-value from the standard z-table:

P-value = 0.02275

A farmer has 1050 yd of fencing to enclose a rectangular pasture for her goats. Since one side of the pasture borders a river,

Dimas [21]

Answer:

Dimensions:

a = 630 yd

b = 210 yd

A = 132.300 yd²

Step-by-step explanation:

Dimensions of rectangular pasture

a and b and a = 3*b a is opposite side at the river, therefore

Area of rectangular pasture

A = a * b and perimeter of rectangular area ( with fencing material ) is

P = a + 2b or P = 3*b + 2*b ⇒ 1050 = 5*b

b = 1050 / 5 ⇒ b = 210 yd

And as a = 3*b ⇒ a = 3*210 ⇒ a = 630 yd

And the area is A = 630*210 = 132.300 yd²
