Based on the z-statistic of –2.5 for the sample data, should the null hypothesis be rejected? Yes, because the z-statistic lies within the critical region. Yes, because the z-statistic lies outside of the critical region. No, because the z-statistic lies within the critical region. No, because the z-statistic lies outside of the critical region.
Answers
Answer:
No, because z-statistics lies within the critical region.
Step-by-step explanation:
The z value is calculated to determine whether the null hypothesis should be accepted or rejected. The null hypothesis is rejected when the z-value lies outside the critical region. The critical region is determined by the sample data.
Answer:
A) Yes, because the z-statistic lies within the critical region.
Step-by-step explanation:
Next one is B) The claim should be rejected.

Given : The probability that a new spark plug is defective is 0.06. You need two new spark plugs.
To find : What is the probability that both spark plugs you buy are defective?
Solution :
Probability of one spark plug being defective is 0.06
We have to find for two defective spark plugs.
This situation is a compound event in which there is more than one possible outcome.
So, The Probability of two spark plug being defective is
Therefore, The Probability of two spark plug being defective is 0.0036.
So, Option C is correct.

The required simplified value of the t in the given proportion is given as t = 48.
What is simplification?
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Given the expression of proportion,
t/16 = 40 / 50
t / 60 = 4 / 5
Multiply both sides by 60,
t / 60 × 60 = 4 / 5 × 60
t = 4 × 12
t = 48
Thus, the required simplified value of the t in the given proportion is given as t = 48.
