Problem 7.013 a random sample of size n1 = 13 is selected from a normal population with a mean of 75 and a standard deviation of 9. a second random sample of size n2 = 9 is taken from another normal population with mean 69 and standard deviation 12. let upper x overscript bar endscripts subscript 1and upper x overscript bar endscripts subscript 2 be the two sample means. find: (a) the probability that upper x overscript bar endscripts subscript 1 baseline minus upper x overscript bar endscripts subscript 2 exceeds 4. (b) the probability that 4.7 less-than-or-equal-to upper x overscript bar endscripts subscript 1 baseline minus upper x overscript bar endscripts subscript 2 baseline less-than-or-equal-to 5.4. round your answers to two decimal places (e. g. 98.76).
