assuming that the system downtime is normally distributed with mean (mu)4.47 sec and standard deviation(sigma) of 0.38 sec. By using the cumulative (to the left) Z score table, a) find the probability that the system downtime is more than 5 sec. z score = (n-mu)/sigma = (5-4.47)/0.38 = 1.39 the probability for 1.39 in the z score table is 0.9177 so, P(x <= 5)= 0.9177 P(x>5)= 1- 0.9177 = 0.0823 b) what is the minimum downtime duration for the worse 5% ? (i already got the answer for a, i just don't quite understand the meaning of 'for the worse 5%' )

What is the range of the function ${\displaystyle y=x^2}$?

The domain and range of $y=\sin <!--\; \; -->x$ is
A)$R,[0,\mathrm{\infty <!--\; \infty \; -->}]$
B)$R,[-<!--\; -\; -->1,1]$
C)$R,[-<!--\; -\; -->\mathrm{\infty <!--\; \infty \; -->},\mathrm{\infty <!--\; \infty \; -->}]$
D)$R,[1,\mathrm{\infty <!--\; \infty \; -->}]$

Mean of the squares of the deviations from mean is called the:
Variance
Standard deviation
Quartile deviation
Mode

A local newspaper in a large city wants to assess support for the construction of a highway bypass around the central business district to reduce downtown traffic. They survey a random sample of 1152 residents and find that 543 of them support the bypass. Construct and interpret a 95% confidence interval to estimate the proportion of residents who support construction of the bypass.
