Please, help me. I need the right answer.

Find the probability for a normal distribution p(-0.80

If Z is a standard normal variable, find the probability. The probability that Z lies between 0 and 3.01

The graph of the normal distribution resembles a "bell" curve. True SAMSUNG & False C $ % * 0

* Your answer is incorrect. Service time for a customer coming through a checkout counter in a retail store is a random variable with the mean of 3.5 minutes and standard deviation of 3.5 minutes. Suppose that the distribution of service time is fairly close to a normal distribution. Suppose there are two counters in a store, n₁ = 2 customers in the first line and n₂ = 13 customers in the second line. Find the probability that the difference between the mean service time for the shorter line X₁ and the mean service time for the longer one X₂ is more than 0.1 minutes. Assume that the service times for each customer can be regarded as independent random variables. Round your answer to two decimal places (e.g. 98.76). P = i 98.80
