Answer:
a) Critical value = -1.285
b) We should reject null hypothesis that the mean equals 0.32
Step-by-step explanation:
Given that the statistic of z equals negative 2.40 is obtained when testing the claim that less than 0.32
i.e. for hypotheses
(one tailed test at 10% significance level)
Z critical value for 90% one tailed = -1.285
Since our test statistic is less than -1.285 we reject null hypothesis
a) Critical value = -1.285
b) We should reject null hypothesis that the mean equals 0.32
Answer:
Step-by-step explanation:
$16,250 is the down payment amount
6x - 17 = 7 ........ added 1x to both sides
6x = 24 ............. added 17 to both sides
x = 4 ................. divided by 6 on both sides
so x=4
Multiplying 37.4 x 0.7 gives you answer less than 37.4 because....
There is one decimal point in 37.4 and one decimal point in 0.7
When multiplied you have to move the decimal point TWO times.
As you move the decimal point to the left the value decreses.
Hope I helped!
