The reading speed of sixth-grade students is approximately normal, with a mean speed of 125 words per minute and a standard devi
Lisa [10]

Answer:

<u>Part A</u>

<u>μ of the reading speed of sixth-grade students = 125 words</u>

<u>σ of the reading speed of sixth-grade students = 24 words</u>

<u>Part B</u>

<u>The probability that a randomly selected sixth-grade student reads less than 100 words per minute is 14.92%</u>

<u>Part C</u>

<u>The probability that a randomly selected sixth-grade student reads more than 140 words per minute is 26.43% </u>

Step-by-step explanation:

Part A:

μ of the reading speed of sixth-grade students = 125 words

σ of the reading speed of sixth-grade students = 24 words

Part B:

1. Let's find the z-score for a randomly selected sixth-grade student that reads less than 100 words per minute:

z-score = (100 - 125)/24

z-score = -25/24

z-score = -1.04

2. Now, let's find out the probability that a randomly selected sixth-grade student that reads less than 100 words per minute, using the z-table:

P (-1.04) = 0.1492

<u>This means that the probability that a randomly selected sixth-grade student that reads less than 100 words per minute is 14.92%</u>

Part C.

1. Let's find the z-score for a randomly selected sixth-grade student that reads more than 140 words per minute:

z-score = (140 - 125)/24

z-score = 15/24

z-score = 0.63

2. Now, let's find out the probability that a randomly selected sixth-grade student that reads more than 140 words per minute, using the z-table:

P (0.63) = 0.7357

But we're being asked for a randomly selected student that reads more than 140 words, then:

1 - P(0.63) = 1 - 0.7357 = 0.2643

<u>This means that the probability that a randomly selected sixth-grade student that reads more than 140 words per minute is 26.43%</u>

The two triangles' area=24*9=216
The bottom side: 40*24=960
The two other sides: 30*40=1200
