Delivery times for shipments from a central warehouse have a right skewed distribution with a mean of 1.97 days (note that times are measured continuously, not just in number of days) and a standard deviation of 1.97 days. A random sample of 71 shipments are selected and their shipping times are observed. Use the Central Limit Theorem to find the probability that the mean shipping time for the 71 shipments is less than 1.69 days. Round your answer to 4 decimal places.

Step 1
69 \) \( \mu = 0.97 \) \( \sigma = 1.97 \) \( n = 71 \) Plugging in the values: \( z = \frac{1.69 - 0.97}{\frac{1.97}{\sqrt{71}}} \) \( z = \frac{0.72}{0.234} \) \( z = 3.08 \) Show more…

Delivery times for shipments from a central warehouse are exponentially distributed with a mean of 2.73 days (note that times are measured continuously, not just in number of days). The standard deviation of an exponential distribution is equal to the mean of 2.73 days. A random sample of 72 shipments are selected and their shipping times are observed. Use the Central Limit Theorem to find the probability that the mean shipping time for the 72 shipments is less than 2.21 days.

Delivery times for shipments from a central warehouse are exponentially distributed with a mean of 2.16 days (note that times are measured continuously, not just in number of days). A random sample of 70 shipments are selected and their shipping times are observed. Approximate the probability that the average shipping time is less than 1.76 days. Enter your answer as a number accurate to 4 decimal places.
