Let p denote the portion of a student’s exam with errors. Suppose we test H0 : p = 0.05 and Ha : p > 0.05 using the following rule. Two problems are chosen at random. If both are error free, we reject H0. If one or both contains an error, we look at a third problem. If the third problem is error free, we reject H0. In all other cases, we fail to reject H0. (a) Explain type I error in the context of this problem. (b) What is the value of α associated with this test? (c) Explain type II error in the context of this problem. (d) Calculate β = P(type II error) as a function of pa, i. e find the value of β(pa) where pa > 0.05.

The data shown in the table below represents the weight, in pounds, of a little girl, recorded each year on her birthday. age (in years) weight (in pounds) 2 32 6 47 7 51 4 40 5 43 3 38 8 60 1 23 part a: create a scatter plot to represent the data shown above. sketch the line of best fit. label at least three specific points on the graph that the line passes through. also include the correct labels on the x-axis and y-axis. part b: algebraically write the equation of the best fit line in slope-intercept form. include all of your calculations in your final answer. part c: use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.

Erinn wrote the equation –5x + 4y = 32 to represent her hourly wage (y) and how this wage has changed during each year that she worked at a company (x). what is the rate of change in erinn's hourly wage per year?
