NEED HELP ASAP TAKING TEST A refrigeration unit at a restaurant is supposed to be kept at 40°F. An inspector would like to test

the hypotheses H Subscript 0 Baseline: mu = 40 versus H Subscript alpha Baseline: mu not-equals40 where μ = the true mean temperature for all times of the day. A 98% confidence interval based upon a random sample of 40 temperatures is 40.5 degrees to 42.1 degrees. Using the interval, what decision should be made?
The null hypothesis should be rejected at the Alpha = 0.01 level.
The null hypothesis should be rejected at the Alpha = 0.02 level.
The null hypothesis should not be rejected at the Alpha = 0.05 level.
The null hypothesis should not be rejected at the Alpha = 0.10 level.

How do I solve this
Veronika [31]

Answer:

P(A or B) = 1.16

Step-by-step explanation:

Given probability:

Probability of event A = P(A) = 0.46

Probability of event B = P(B) = 0.7

P(A and B) = 0.43

Find:

P(A or B)

Computation:

If A is an incident and B is a separate event, P(A or B) is the possibility of either A, B, or both events occurring.

P(A or B) = P(A) + P(B)

P(A or B) = 0.46 + 0.7

P(A or B) = 1.16

Find the value of x.........
GREYUIT [131]
The angles of a triangle should add up to 180 degrees. in the left triangle, you should find the 3rd angle

75 + 50 + y = 180
125 + y = 180
y = 55

vertical angles are congruent, so the left angle on the right triangle will also be 55 degrees. 

then you do the same thing to find x.

85 + 55 + x = 180
140 + x = 180
x = 40
