Part 1: What is the range of the data set?

Part 2: What is the interquartile range of the data set?

Part 3: What is the mean absolute deviation of the data set? [Round both the mean and the mean absolute deviation to the nearest tenth.]

1.The following dot plot represents student scores on the Unit 1 math test. Scores are in whole number increments. If the test was out of 20 points, about what percentage of the students scored at least 80% on the test?

a.48%
b.67%
c.17%
d.12%

2.The following dot plot represents student scores on the Unit 1 math test. Scores are in whole number increments.
Part 1: What is the mean score, rounded to the nearest whole number?

Part 2: What is the median score?

Part 3: What is the mode score?

3.The following dot plot represents student scores on the Unit 1 math test. Scores are in whole number increments.

For this data set, the value of the range is about(CHOOSE: the same as or triple, or twice) the value of the interquartile range.

On average, the data points lie between(CHOOSE: 3 and 4 or 5 and 6 or 1 and 2 or 2 and 3 or 4 and 5) points from the mean.

Step-by-step explanation:

Given:

Glyder's Parachutes manufactures and sells parachutes of various types and prices. Also  3 charts prepared at the end of the year

I chart between days of production and Number of

Parachutes Produced shows that when former increases, the latter also increases.

Hence direct variation

II chart between  Purchase Price

of Parachute  and Number of

Parachutes sold:

Here when purchase price increases ,sales price also will increase resulting in less number of sales.

Hence indirect variation

III CHart shows that  that the purchase price of a parachute with the cost to produce the parachute.

Here when apurchase price of a parachute increases, automatically cost to produce would increase.

Hence direct variation
