Determine the critical values for these tests of a population standard deviation. (a) a right-tailed test with 1818 degrees of freedom at the alphaαequals=0.050.05 level of significance (b) a left-tailed test for a sample of size nequals=2929 at the alphaαequals=0.010.01 level of significance (c) a two-tailed test for a sample of size nequals=3131 at the alphaαequals=0.010.01 level of significance(a) the critical value for this right-tailed test is nothing

step-by-step explanation:

70 years.

step-by-step explanation:

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75
