I need help with these problems. Theyre supposed to be done in excel but I have no idea what formulas to use. The software is very sensitive to rounding.

Given a normal distribution with 100 and -10, complete parts (a) through (d). EEB Click here to view page 1 of the cumulative standardized normal distribution table EEB Click here to view page 2 of the cumulative standardized normal distribution table. a. What is the probability that X> 75? The probability that X>75 is 0.9938 (Round to four decimal places as needed.) b. What is the probability that X 105? The probability that X 105 is 0.3099 (Round to four decimal places as needed.) d. 90% of the values are between what two X-values (symmetrically distributed around the mean)? 90% of the values are greater than and less than L. (Round to two decimal places as needed.)
