The probability distribution of x, the number of imperfections per 10 meters of a synthetic fabric in con- tinuous rolls of uniform width, is given in exercise 3.13 on page 112 as x01234 f (x) 0.41 0.37 0.16 0.05 0.01 find the average number of imperfections per 10 meters of this fabric.

A, at (-2, 4), is 6 .of a'? (-8, 4) (-8, -2) (-2, -2) (-2, 4) b, at (-4, -7), isy-.of b'? (-4, 7) (4, -7) (4, 7) (-4, -7)

You are riding your bike and notice the square sign above. you mentally draw a straight line from point a to c. describe the angle relationship between dca and bca

Now, martin can reasonably guess that the standard deviation for the entire population of people at the mall during the time of the survey is $1.50. what is the 95% confidence interval about the sample mean? interpret what this means in the context of the situation where 95 people were surveyed and the sample mean is $8. use the information in this resource to construct the confidence interval.
