STAT 150 The amount X, in GBs, of mobile data Sam uses in a given month is uniformly distributed between 0 and 10. The mobile data plan Sam is subscribed to charges Y dollars per months, where
Y = 20 X < 3，
=10 [X], 3 ≤ X < 6,
=10X X ≥ 6.
where [X] denotes the floor of x.
(1) What is the probability P (Y < 45)?
(2) What is the E(Y)?

Data are given below on the adjusted gross income x and
the amount of itemized deductions taken by taxpayers. Data were
reported in thousands of dollars. With the estimated regression
equation = 4.68 + .16x, the point estimate of a
reasonable level of total itemized deductions for a taxpayer with
an adjusted gross income of $52.5 thousand is $13.08
thousand.

Given: Assume you have collected data from 150 subjects, and
that the distribution of the data is a "normal" distribution. The
mean of the scores is 37, with a standard deviation of 4.5. Using
the given information, calculate the 68% confidence interval. A
confidence interval represents a range of values, the lowest value
is references as the "lower bound", the highest value is referenced
as the "upper bound". Determine the lower and upper bounds for the
68% confidence interval. Round...
