Answer:
Step-by-step explanation:
Given that a lorida poll asked 1200 Floridians whether they would prefer an increase in taxes or a decrease in government services as a way to balance the budget.
(Right tailed test)
STd error assuming H0 to be true = for n =1200
Mean difference =0.02
Test statistic =1.386
p value = 0.0823
5) If n =2500, std error would be = 0.01
Test statistic Z = 2
p value = 0.25
6kg cost 27
1kg cost 4.5
13kg X 4.5= 58.5
Answer:
0.92 and 1.25 respectively
Step-by-step explanation:
0.92 and 1.25 respectively
first the mean of each value which is 9.7 and 9.8 respectively
standard deviation = square root of the mean deviation of each value
then deduct the mean from each element
and square each value and add them together. not you should square each deviation value before you add them
at last divide the result by the number of frequency and find it's square root
If you would like to know which expression represents the amount of time Joe exercises, you can calculate this using the following steps:
Keith ... x hours a week
Troy ... three hours less than Keith: x - 3
Joe ... two times more than Troy: 2 * (x - 3)
The correct result would be D) 2 * (x - 3).
