Can someone please help me with this. Thank you much! 1. A population has parameters μ=36.3 and σ=57. You intend to draw a random sample of size n=139. What is the mean of the distribution of sample means? μ¯x=________________ b. A population of values has a normal distribution with μ=201.8 and σ=90.9. You intend to draw a random sample of size n=20. Find the probability that a single randomly selected value is less than 266.8. P(X < 266.8) _________________
Can you please help me answer and understand this problem?

The shape of the distribution of the time required to get an oil change at a 20 minute oil change facility is unknown. However, records indicate that the mean time is 214 minutes, and the standard deviation is 35 minutes. Complete parts (a) through (c) (a) To compute probabilities regarding the sample mean using the normal model, what size sample would be required?...
