A random sample of 41 subjects who identified themselves as compulsive buyers was obtained and given a questionnaire. They had a mean questionnaire score of 0.60 with a standard deviation of 0.14. Test the claim that the population of self-identified compulsive buyers has a mean greater than the mean of 0.58 for the general population. Use a 0.05 significance level.

answer: the common difference is -0.10

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

the bolded word " farsighted" could be replaced with visionary.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
