Ho: P-HatTeens – P-HatAdults ne 0
C. Ho: PTeens – PAdults = 0
Ho: PTeens – PAdults > 0
D. Ho: PTeens – PAdults = 0
Ho: PTeens – PAdults < 0
- What is the p-pooled?
A. .244 or 24.4%
B. .24 or 24%
C. .25 or 25%
D. No answer text provided.
- How many standard deviations away from the null is the difference between your sample proportions?
A. 0.01 or 1%
B. .18
C. 0.055
D. 85.72%
- What is your conclusion?
A. Fail to reject. There is not a statistically significant difference between the percent of adults and teens who liked the product.
B. Reject the null. The percent of teens and adults that like the product is different.
C. Fail to reject the null. There is a statistically significant difference in the percent of teens and adults that like the product.
D. Reject the null. There is no difference in the percent of adults and teens that like the product.
- What is the p-value?
A. 85.72%
B. 42.86%
C. 14.28%
D. 57.14%

/in Uncategorized /by developerImagine that you have a 5.00 L gas tank and a 3.00 L gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch. If you fill the larger tank with oxygen to a pressure of 155 atm , to what pressure should you fill the acetylene tank to ensure that you run out of each gas at the same time? Assume ideal behavior for all gases.

Imagine That You Have A Drunk Man Moving Along The Horizontal Axis That Stretche
/in Uncategorized /by developerImagine that you have a drunk man moving along the horizontal axis (that stretches from x = −∞ to x = +∞).At time t = 0, his position on this axis is x = 0. At each time point t = 1, t = 2, etc., the man moves forward(that is, x(t +1) = x(t)+1) with probability 0.5, backward (that is, x(t +1) = x(t)−1) with probability 0.3,and stays exactly where he is (that is, x(t +1) = x(t)) with probability 0.2.
(a) Calculate the probability of each possible position at t = 2.
(b) If you know the probability of each position at time t, how will you find the probabilities at time t +1?
(a)The probability associated with each of these positionscan be calculated from theprobabilities that we just computed above (for the man’sposition at time t = 1). (b)
