Let X equal the number of pounds of butterfat produced by a Holstein cow during the 305-day milking period following the birth of a calf. We shall test the null hypothesis 22 22 H0 : σ = 140 against the alternative hypothesis H1 : σ > 140 at α = 0.05, based on given data: n = 25, and a sample standard deviation of s = 150.1. What is the type of the test?A) Right-tailedB) Left-tailedC) Two-tailed2. Calculate Observed Test Statistic3. Find the Critical Value of Critical Region of the Test4. Draw Your Conclusion of the Test at α = 0.05A) Fail to Reject H0B) Reject H0

Step-by-step explanation:

Given that:

1. This type of test is right tailed since the alternative hypothesis is right tailed

2. The Observed test statistic is calculated as follows:

3. Critical Value

where ∝ = 0.05 and the test statistic is right tailed ;

By using   table

4. Conclusion:

∝ = 0.05

where

X² = 36.415

Therefore ; we reject

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )
