An advertisement for a popular weight-loss clinic suggests that participants in its new diet program lose, on average, more than 11 pounds. A consumer activist decides to test the authenticity of the claim. She follows the progress of 24 women who recently joined the weight-reduction program. She calculates the mean weight loss of these participants as 11.8 pounds with a standard deviation of 2.7 pounds. The test statistic for this hypothesis would be __________. Multiple Choice 1.78 −1.45 1.45 −1.78
What is the main confound in an AM-PM/PM-AM study design? It does not control for the effects of sleep deprivation. It does not control for the time passing between training and testing. It does not control for individual variability across participants. It does not control for the time of day when training/testing occurs.

Now let's see what we can tell from an equation for position: x(t) = 6t^2 + 4.2t + 9 What is the object's initial position? Assume each term has units of meters, and that time is in seconds (so everything we ask for is in the usual units). m
(c) Determine the largest open rectangle in the ty-plane that contains the point $(t_0, y_0)$ and in which the hypotheses of Theorem 2.2 are satisfied. 1. $3y' + 2t \cos y = 1$, $y(\frac{\pi}{2}) = -1$ 2. $3ty' + 2 \cos y = 1$, $y(\frac{\pi}{2}) = -1$ 3. $2t + (1 + y^2)y' = 0$, $y(1) = 1$ 4. $2t + (1 + y^3)y' = 0$, $y(1) = 1$ 5. $y' + ty^{1/3} = \tan t$, $y(-1) = 1$ 6. $(y^2 - 9)y' + e^{-y} = t^2$, $y(2) = 2$ 7. $(\cos y)y' = 2 + \tan t$, $y(0) = 0$ 8. $(\cos 2t)y' = 2 + \tan y$, $y(\pi) = 0$

The demand for packs of baseball cards is given by the equation Q = 500,000 - 45,000P. For all parts below, show your work or insert an image of the work. a.) At a price of $2.50, what is the quantity demanded? b.) At $5.00 per pack, what is the price elasticity of demand? Determine/explain what this means about the elasticity of baseball cards at $5.00.
8) A restaurant wants to estimate the proportion of customers who are satisfied with their service. They want to be 95\% confident that their point estimate for the true proportion $p$ will be within 3.2\%. If there is no preliminary study made to estimate the proportion of satisfied customers, what should be the minimum sample size the restaurant needs for its study? (8 pts)
