Hello. I am in need of a step by step approach to calculate the following questions in order that I can apply the approach/logic to similar questions.

The amount of glue a machine pours into bottles has a mean of 50 ounces with a standard deviation of 0.25 ounces. We take a random sample of 36 bottles filled by this machine. True or False the sampling distribution of the sample mean has a mean of 50 ounces. (I think the answer is true).

The amount of time it takes to finish test is negatively skewed distribution with a mean of 70 minutes and a standard deviation of 8 minutes. If 64 students were randomly sampled, the probability that the sample mean of the sampled students exceeds 73.5 minutes is approximately 0. True or False. (Again, I think the answer is true)
