a. Which exam did most students attempt?

i. Move 'Test name' field to row in the pivot table. Also move test scores field to the value table.

ii. This by default will give you the sum of scores. Click on the field under 'value' table and change it from 'sum of values' to 'count of values'

<em><u>The answer is GMAT taken by 13 students</u></em>

<em></em>

b. Which exam has the highest average score?

i. From the pivot table created in part a, change the field setting to 'Average' instead of count.

<u><em>The answer is GMAT with 499.07 average</em></u>

<u><em /></u>

c. Use the pivot table to determine the exam attempted by the student with highest score

i. In the pivot created above, change field setting to 'Max'

<u><em>The answer is MCAT with 589</em></u>

What is the exam attempted by the student with lowest score.

larisa [96]

<span>With algebraic expressions, you can’t add and subtract any terms like you can add and subtract numbers. Terms must be like terms in order to combine them. So, you can’t always simplify an algebraic expression by following the order of operations. You have to use the distributive property to rewrite the expression and then combine like terms to simplify. With numeric expressions, you can either simplify inside the parentheses first or use the distributive property first.</span>

Tanzania [10]

Answer:

Approximately, 159 men weighs more than 165 pounds and 159 men weighs less than 135 pounds.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 150 pounds

Standard Deviation, σ = 15

We are given that the distribution of weights of 1000 men is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P( men weighing more than 165 pounds)

P(x > 165)

$P( x > 165) = P( z > \displaystyle\frac{165 - 150}{15}) = P(z > 1)$

$= 1 - P(z \leq 1)$

Calculation the value from standard normal z table, we have,

$P(x > 165) = 1 - 0.8413 = 0.1587 = 15.87\%$

Approximately, 159 men weighs more than 165 pounds.

P(men weighing less than 135 pounds)

P(x < 135)

$P( x < 135) = P( z < \displaystyle\frac{135 - 150}{15}) = P(z < -1)$

Calculation the value from standard normal z table, we have,

$P(x < 135) = 0.1587 = 15.87\%$

Approximately, 159 men weighs less than 135 pounds.
