Hi i need help with these questions. Thank you

Note: M is used to represent the Mean of the sample Means, X , for this question. The lengths of pregnancies in a small rural village are normally distributed with a mean of 261.7 days and a standard deviation of 12.2 days. In what range would you expect to find the middle 50% of most pregnancies? Round z-scores to two decimal places. All other intermediate calculations should be to 4 decimal places, if needed. Between and If you were to draw samples of size 58 from this population, in what range would you expect to find the middle 50% of most averages for the lengths of pregnancies in the sample? Round z-scores to two decimal places. All other intermediate calculations should be to 4 decimal places, if needed. Between and When asked:"What is the distribution of X ? X -N(,_)." This notation is referring to N, a normal distribution, with the mean given in the first space and the standard deviation in the second space. Remember that the standard deviation of the sample means is different from the population standard deviation. A population of values has a normal distribution with u = 125 and o = 67.1. You intend to draw a random sample of size n = 195. Find the probability that a single randomly selected value is less than 109.6. P(X
