A can of soda costs $1.20 in the United States and 30 pesos in Mexico. Assume purchasing-power parity holds. The peso–dollar exchange rate is pesos per dollar. Suppose a monetary expansion causes all prices in Mexico to double, so that the price of soda in Mexico rises to 60 pesos. The peso–dollar exchange rate is now pesos per dollar.

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

a
