This histogram shows the distribution of exam scores for a class of 33 students. which of the following is the most reasonable estimate for the median 50, 75, or 85?​

Answers

Answer 1

Answer:

[tex]Median = 75[/tex]

Explanation:

Given

[tex]n = 33[/tex]

See attachment for histogram

Required

Determine the median

Median is calculated as:

[tex]Median = \frac{n+1}{2}th[/tex]

[tex]Median = \frac{33+1}{2}th[/tex]

[tex]Median = \frac{34}{2}th[/tex]

[tex]Median = 17th[/tex]

From the histogram, the 17th entry fall in the class: 70 - 80

In this case: the median is the average of 70 and 80

So:

[tex]Median = \frac{1}{2}(70 + 80)[/tex]

[tex]Median = \frac{1}{2}(150)[/tex]

[tex]Median = 75[/tex]

Suppose y is inversely proportional to x. If y = –8 when x = –2, find y when x = 32

Answers

Answer: 1/2

Explanation:

When y is inversely proportional to x. This implies that:

y = k/x

If y = –8 when x = –2, then the constant of proportionality will be;

y = k/x

-8 = k/-2

k = (-8 × -2)

k = 16

when x = 32, the value of y will be:

y = k/x

y = 16/32

y = 1/2

Smell: Spring brings soothing scents like lilacs, apple blossoms, hyacinth and daffodils. Sweet aromas turn a stroll through the garden into a delicacy for the nose Springtime means that the trees and flowers come back to life again. After a dead winter, this is a time when we get to see the beautiful flowers blossom again Spring also brings new sounds, like bird songs at dawn, frog croaks by ponds, and dripping icicles.

Question:

For a population with a mean of μ=45 and a standard deviation of σ=10. What is the corresponding z score if it has a score of X = 44?

Answer:

[tex]z = -0.10[/tex]

Explanation:

Given

[tex]\mu = 45[/tex]

[tex]\sigma = 10[/tex]

[tex]x = 44[/tex]

Required

Calculate the z score

This is calculated as:

[tex]z = \frac{x - \mu}{\sigma}[/tex]

So:

[tex]z = \frac{44 - 45}{10}[/tex]

[tex]z = \frac{-1}{10}[/tex]

[tex]z = -0.10[/tex]
