The head of maintenance at XYZ Rent-A-Car believes that the mean number of miles between services is 3408 miles, with a variance of 249,001. If he is correct, what is the probability that the mean of a sample of 36 cars would be less than 3245 miles

Answers

Answer:

The probability that the mean of a sample of 36 cars would be less than 3245 miles

P(X⁻≤3245) = 0.975

Step-by-step explanation:

Step(i):-

The mean number of miles between services

                   μ= 3408 miles  

The Variance of miles between services

                σ² = 249,001

                σ = √249,001 = 499

Let 'X' be a random variable in a normal distribution

Given sample size 'n' =36

Step(ii):-

           [tex]Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }[/tex]

          Z = -163/83.16 = 1.96

The probability that the mean of a sample of 36 cars would be less than 3245 miles

P(X⁻≤3245)  =   P(Z≤1.96)

                   =   0.5 + A(1.96)

                   =  0.5 + 0.4750

                  =   0.975

Final answer:-

The probability that the mean of a sample of 36 cars would be less than 3245 miles

P(X⁻≤3245) =0.975

HELP!!!! Read the following story carefully, and then complete the activities that follow.

"Good-bye, Mom," Tino cried as he rushed out the door. Tino had his new fishing pole with him and was anxious to try it out.

Tino Kanaha (kan' ah hah) was a Hawaiian boy. He had just turned twelve the day before and had received the fishing pole as a gift from his father.

Tino's house was about a half mile from the cliff overlooking the leeward side of Maui. Many times Tino had climbed down to the rocks below and looked for seashells while his father fished for aku.

"Now it's my turn," thought Tino as he scurried out onto one of the rocks, "and I get to do it all by myself!"

"Aku, here I come!" yelled Tino excitedly as he cast his bait into the surf.

An hour later, Tino heard someone call his name. He looked up and saw his good friend, Kona. "Have you caught anything?" Kona yelled.

"Oh, hi, Kona," Tino said disappointedly. "Wait for me, and I'll be right up."

As Tino reeled in his line, he noticed the waves were much bigger than they had been before. "The wind is stronger, too, " thought Tino as he glanced at the darkening sky.

"We'd better hurry home," Tino said to Kona as he reached the top of the hill. The two boys ran as quickly as they could. They even took the short cut through the sugar cane field to save time.

Kona raced into his yard and, without stopping, he yelled, "Good-bye, Tino! I'll see you tomorrow!"

The first big drops of rain began to fall as Tino reached the front door of his house.

"Oh, I'm glad you're home!" Mrs. Kanaha said. "It is beginning to rain very hard!"

"The storm must be the reason the fish weren't biting," Tino said as he put his fishing pole into the rack on the porch, "but I'll try again tomorrow."



Give two details that are clues that Tino did not catch any fish.

Answers

Detail 1: In the second to last paragraph Tito states that “the storm must be the reason the fish weren’t biting” indicating that the he didn’t catch any fish

Detail 2: When Tito’s friend Mona asks “Have you caught anything ?” Tito doesn’t answer the question and only says “Oh hi Kona” which shows that he didn’t catch a fish yet
Clue #1 - “Oh, hi, Kona,” Tino said DISAPPOINTEDLY. “Wait for me, and I’ll be right up.”

Clue #2- “The storm must be the reason THE FISH WERENT BITING,” Toni said as he put his fishing pole into the rack on the porch, “but I’ll try again tomorrow.”
