In a test of hypotheses H0: µ = 212 versus H1: µ > 212, the rejection region is the interval [1.895, [infinity]), the value of the sample mean computed from a sample of size 10 is 225, and the value of the test statistic is t = 2.44. The correct decision and justification are:

10x10.gif A 10x10.gif Do not reject because 2.44 is greater than 1.895
B Reject because 225 is larger than 212
C Reject because 2.44 falls in the rejection region
D Do not reject because 2.44 falls in the acceptance region
E Do not reject because the sample size of 10 is too small

i those same problems in math and dont know how to do them

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
