Answer:

y+2 = 1/5(x - 7)

Step-by-step explanation:

Point slope form

(y-y1)= m(x-x1)

m= 1/5

x1 = 7

y1 = -2

(y- (-2)) = 1/5(x-7)

y+2 = 1/5(x - 7)

When it is operating properly, a chemical plant has a daily production rate that is normally distributed with a mean of 885 tons

-BARSIC- [3]

Answer:

The test statistic Z = 1.844 < 1.96 at 0.05 level of significance

Null hypothesis is accepted

Yes he is right

The manager claims that at least 95 % probability that the plant is operating properly

Step-by-step explanation:

Explanation:-

Given data Population mean

μ = 885 tons /day

Given random sample size

n = 60

mean of the sample

x⁻ = 875 tons/day

The standard deviation of the Population

σ = 42 tons/day

Null hypothesis:- H₀: The manager claims that at least 95 % probability that the plant is operating properly

Alternative Hypothesis :H₁: The manager do not claims that at least 95 % probability that the plant is operating properly

Level of significance = 0.05

The test statistic

$Z = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }$

$Z = \frac{875 -885}{\frac{42}{\sqrt{60} } }$

$Z = \frac{-10}{5.422} = -1.844$

|Z| = |-1.844| = 1.844

The tabulated value

$Z_{\frac{0.05}{2} } = Z_{0.025} = 1.96$

The calculated value Z = 1.844 < 1.96 at 0.05 level of significance

Null hypothesis is accepted

Conclusion:-

The manager claims that at least 95 % probability that the plant is operating properly

Inheritance is the tradition of transferring on private property, rights, debts, titles, and responsibilities upon the death of a person. In law, an heir is a character who is authorized to obtain a share of the deceased's (the personality who died) property, subjected to the rules of heritage in the jurisdiction of which the departed was a resident or where the departed (decedent) died or occupied property at the time of death. The inheritance may be either below the duration of a will or by inter-state laws if the departed had no will. However, they will need to comply with the laws of particular jurisdiction at the time it was formulated or it will be announced invalid and the intestate rules then apply.
