You fit a trendline of y = 2x 1 to your data. what would the residual be for a data point measured as y = 3.5 for an x value of

nata0808 [166]

For a data point measured as y = 3.5 for an x value of x = 1.2, the residual would be 0.1

For given question,

we have been given an equation 2x + 1 that represents an equation for a trendline to the data.

General formula with residual is y = 2x + 1 + r, where r is a residual.

We need to find the residual for a data point measured as y = 3.5 for an x value of x = 1.2

We substitute given values of x and y in the residual equation

y = 2x + 1 + r

For y = 3.5 and x = 1.2,

⇒ 3.5 = 2(1.2) + 1 + r

⇒ 3.5 = 2.4 + 1 + r

⇒ r = 3.5 - 3.4

⇒ r = 0.1

Therefore, for a data point measured as y = 3.5 for an x value of x = 1.2, the residual would be 0.1

A poll asks shoppers at the mall how many cups of water they typically drink in a day. The results of the poll are listed below.

juin [17]

Answer:

D 9.5

Step-by-step explanation:

Write data in increasing order.

3, 5, 5, 6, 6, 6, 7, 7, 8, 8, 8, 8, 8, 8, 9, 9, 10, 10, 10, 10, 11

Find the median

3, 5, 5, 6, 6, 6, 7, 7, 8, 8, 8, 8, 8, 8, 9, 9, 10, 10, 10, 10, 11

Median is 8

Lower half of the data is : 3, 5, 5, 6, 6, 6, 7, 7, 8, 8,

First quartile is the median of the lower half of the data=6+6 /2 =6

Upper half of the data is: 8, 8, 8, 9, 9, 10, 10, 10, 10, 11

The Third quartile is the median of the upper half=9+10 / 2 = 9.5
