NBC News reported on May 2, 2013, that 1 in 20 children in the
United States have a food allergy of some sort. Consider selecting
a random sample of 15 children and let X be the number in
the sample who have a food allergy. Then X ~ Bin(15,
0.05). (Round your probabilities to three decimal places.)
(a)
Determine both P(X ≤ 3) and
P(X < 3).
P(X ≤ 3)
=
P(X < 3)
=
(b)
Determine P(X ≥ 4)....

Consider the population of all 1-gallon cans of dusty rose paint manufactured by a particular paint company. Suppose that a normal distribution with mean μ = 6 ml and standard deviation σ = 0.2 ml is a reasonable model for the distribution of the variable x = amount of red dye in the paint mixture. Use the normal distribution model to calculate the following probabilities. (Round your answers to four decimal places.) (b) P(x < 6.2)= (d) P(5.6 < x...

1.) Accrotime is a manufacturer of quartz crystal watches.
Accrotime researchers have shown that the watches have an average
life of 30 months before certain electronic components deteriorate,
causing the watch to become unreliable. The standard deviation of
watch lifetimes is 10 months, and the distribution of lifetimes is
normal.
(a) If Accrotime guarantees a full refund on any defective watch
for 2 years after purchase, what percentage of total production
will the company expect to replace?
(b) If Accrotime...
