A stress analysis was conducted on random samples of epoxy-bonded joints from two species of wood. A random sample of 120 joints from species A had a mean shear stress of 1250 psi and a standard deviation of 350 psi, and a random sample of 90 joints from species B had a mean shear stress of1400 psi and a standard deviation of 250 psi. Find a 98% confidence interval for the difference in mean shear stress between the two species

Jeremiah is tracking how many customers he can assist in an afternoon. He listed the number of customers assisted per hour in the following table:Determine if these data represent a linear function or an exponential function, and give the common difference or ratio.A - This is an exponential function because there is a common ratio of 2.B - This is a linear function because there is a common difference of 4.C - This is an exponential function because there is a common ratio of 4.D - This is a linear function because there is a common difference of 2

There are 15 balls in an urn. 7 of the balls are red, and 8 of the balls are blue. Drawing a ball with replacement means that you take a ball out, note its color, and then return it. Drawing withoutreplacement means that you take a ball out and do not put it back. (a) What is the probability that if you draw one ball, it will be blue?(b) If you draw two balls without replacement, what is the probability that you draw a red and then a blue?(c) If you draw two balls with replacement, what is the probability that you draw a red and then a blue?(d) If you draw three balls without replacement, what is the probability that you draw at least two red balls?(e) If you draw three balls with replacement, what is the probability that you draw at least two red balls?(f) We play a game where I draw a ball first without replacement, and then you draw one. I draw a blue ball, and then you draw a red ball. Are these events independent?

You and your best friend Janine decide to play a game. You are in a land of make believe where you are a function, f(t), and she is a function, g(t). The two of you move together throughout this land with you (that is, f(t) ) controlling your East/West movement and Janine (that is, g(t) ) controlling your North/South movement. If your identity, f(t), is given by f(t)=(t2+10)323 and Janine's identity, g(t), is given by g(t)=5t then how many units of distance do the two of you cover between the Most Holy Point o' Beginnings, t=0, and The Buck Stops Here, t=20?
