3. a random sample of 100 records in a us city during the past year showed an average life span of 71.8 years. a. assuming normality and a population standard deviation of 8.9 years, does this seem to indicate that the mean life span today is not different than 70 years ? use a 0.10 level of significance and write hypothesis testing steps explicitly. b. find the p-value that corresponds to the test statistic. would you reject h0 by using the p-value? why ?

answer: f = 32.2m

step-by-step explanation: that is the answer

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

answer: the four apples you took away.

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
