Suppose that a regression line for some data transformed with logarithms predicts that when x equals 4, log(y) will equal 3.331. what does the regression line predict y will equal when x equals 4? round your answer to the nearest whole number.

a. 101

b. 13

c. 3

d. 2143

Option D

The regression line predicts that at x = 4, y equals 2143

Solution:

Given that when x equals 4, log(y) will equal 3.331

To find: Find y when x equals 4

Since we have given that,

When x = 4,

We need to find the value of 'y' when x = 4

Since it is logarithmic function with base 10, Raise to power of 10 on both sides,

On rounding to nearest whole number, we get 2143

Thus Option D is correct

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
