1) The null hypothesis represents the condition that will be assumed to be true unless sufficient
evidence is presented to show that the condition has changed.
True.
2) A P-value greater than the chosen level of significance results in concluding the null hypothesis is
true...

If X ~ N(22,4), z = (x - 22)/sqrt(4) ~ N(0,1) Thus, P(22 <= X <= 25) = P((22-22)/2 <= z...
Consider a one-sided (greater than) hypothesis tests. For a given level of significance we can find the quantile which satisfies
From the standard Normal Table, find the approximate quantiles for and and indicate which of the following statements is correct.Select one:

f(t) = 7H(t) + bH(t-5)
when t = 5
f(5) = 49 + 7b
15 = 49 + 7b
-34 = 7b
b = -34/7

Integrating from 0 to infinity and equating it to 1, we get
(c/2*10^-3) = 1
c= 2/1000
=0.002
Is it correct?

3^3 * 3^( i8pi/ln(3) ) = 27 * (3^ i8pi - 3^ln(3) ) = 27 *( 3^25.1i -3.34)
= 3^(3+ i25.1) - 90.26
If this is correct how can I convert this to a number...
