22 The average age for licensed drivers in the country is u = 42.6 years with a standard deviation of = 12. The distribution is approximately normal
a. A researcher obtained a sample of n = 25 drivers who received parking tickets. The average age
for these drivers was M = 40.5. Is this a reasonable outcome of a sample of n=25, or is the sample
mean very different from what would normally be expected? (Hint: Compute the z-score for the
sample mean )
b. The same researcher also obtained a sample of n = 12 drivers who received speeding tickets. The
average age for this sample was M = 34.4. Is this a reasonable outcome for a sample of n= 16, or is
the sample mean very different from what would usually be expected? (Again, compute the z-score
for the sample mean.)​

In 2007, americans smoked 19.2 billion packs of cigarettes. they paid an average retail price of $4.50 per pack. a. given that the elasticity of supply is 0.50.5 and the elasticity of demand is negative 0.4−0.4, derive linear demand and supply curves for cigarettes. the demand equation is qdequals=nothingplus+nothing times ×p and the supply equation is qsequals=nothingplus+nothing times ×p.

(do not round intermediate calculations. input your answers as a percent rounded to 2 decimal places.) a-2. which loan should summit accept? southwest bank fidelity bank b. recompute the effective cost of interest, assuming that summit ordinarily maintains $37,680 at each bank in deposits that will serve as compensating balances
