On a planet far far away from Earth, IQ of the ruling species is
normally distributed with a mean of 111 and a standard deviation of
17. Suppose one individual is randomly chosen. Let X = IQ of an
individual.
a. What is the distribution of X? X ~ N(,)
b. Find the probability that a randomly selected person's IQ is
over 114. Round your answer to 4 decimal
places.
c. A school offers special services for all children in the bottom
7% for IQ scores. What is the highest IQ score a child can have and
still receive special services? Round your answer to 2
decimal places.
d. Find the Inter Quartile Range (IQR) for IQ scores. Round
your answers to 2 decimal places.

1. X ~ N(50, 12). Suppose that you form random samples of 25 from this distribution. Let X be the random variable of averages. Let ΣX be the random variable of sums.Sketch the graph, shade the region, label and scale the horizontal axis for X, and find the probability. (Round your answer to four decimal places.) P(8 < X < 47) = 2.Some statistics students estimated that the amount of change daytime statistics students carry is exponentially distributed with a...
