PLEASE ANSWERRRRRRRRRRRRR
Sunny_sXe [5.5K]

Answer:

y = 23x-82

Step-by-step explanation:

The equation is written in the form y = mx+b

We need to find the slope

m = (y2-y1)/(x2-x1)

   = (79-56)/(7-6)

   = 23/1

The slope is 23

y= 23x +b

Put in a point for x and y to determine b

10 =23(4) +b

10 =92 +b

Subtract 92 from each side

10-92 = 92-92 +b

-82 =b

The equation is

y = 23x-82

Answer:

No, because all the expected frequencies must be higher than 5.

Step-by-step explanation:  

The chi-square test might be performed in those situations in which we need to know if a series of observations adjust or not to a theoretical function, such as the normal, Poisson, or binomial.

The chi-square test does not require the number of files to coincide with the number of columns in the table. It does not establish any restriction about the number of modalities per variable. However, the expected frequencies or counts should not be less than five.

In the exposed example, this unique rule is not accomplished, so the chi-square test can not be performed.
