Rob Raydo, a data analyst in a certain bank, found that the mean amount of credit card debt per household in households having credit card debt is 30,000 pesos with a standard deviation of 25,000 pesos. Find the probability that the mean amount of credit card debt in a sample of 100 households is less than 25,000 pesos. 2. Moore Reno, an officer in the highway patrol group, observed that the speeds of vehicles on a particular stretch of a specific highway are normally distributed with a mean of 90 kph and a standard deviation of 50 kph. Find the probability that the mean speed of 25 randomly selected vehicles is between 75 and 100 kph.
