thats your answer
Let x be a random variable representing the mean thickness of alutin.
a.) P(2.97 < x < 3.08) = P((2.97 - 3.05)/0.025 < z < (3.08 - 3.05)/0.025) = P(-3.2 < z < 1.2) = P(z < 1.2) - P(z < -3.2) = P(z < 1.2) - [1 - P(z < 3.2)] = P(z < 1.2) + P(z < 3.2) - 1 = 0.88493 + 0.99931 - 1 = 0.88424
Answer: -6 That’s your answer.

Answer:
hours worked at job, number of siblings are examples of discrete random variable.
Step-by-step explanation:
Discrete random variable has values that can be counted. It has finite data that does not change continuously.
Hours worked at a job can be counted at the end of the day.
The weight of a child keeps changing continuously therefore it is not a discrete random variable.
Number of siblings can be counted.
The length of a fish can keep changing day by day therefore it is not a discrete random variable.
