D. 1/2 due to the fact that 10 would be over 20 so 10/20 and simplified is 1/2.
Answer:
PY = 8
Step-by-step explanation:
Lets run down the other three to show why they're wrong
<em>MY=8</em>
By P.T, that's wrong (PERPENDICULAR)
<em>PM=MY </em>
We can't prove that with the given
XY=42
Again, by P.T., this is false
BTW: You can prove PY=8 by proving XMP congruent to YMP by SAS
Answer:
We conclude that the plant should shut down.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 60
Sample mean,
= 61.498
Sample size, n = 100
Alpha, α = 0.05
Population standard deviation, σ = 6
a) First, we design the null and the alternate hypothesis such that the power plant will be shut down when the null hypothesis is rejected.
We use One-tailed(right) z test to perform this hypothesis.
b) Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and accept the alternate hypothesis. Thus, the temperature of waste water discharged is greater than 60°F. We conclude that the power plant will shut down.
Calculating the p-value from the z-table:
P-value = 0.0063
Since,
P-value < Significance level
We reject the null hypothesis and accept the alternate hypothesis. Thus, the temperature of waste water discharged is greater than 60°F. We conclude that the power plant will shut down.
