Answer:
it is 27
Step-by-step explanation:
Solution :
This is the two tailed test.
The null hypothesis and the alternate hypothesis is as :
Null hypothesis is 
Alternate hypothesis is 

Therefore, the critical value of z is :

Now the test statics is :



The test statics is 0.878
We see that it is a right tailed test.


= 0.3800
Thus , P-value > α
So we fail to reject the null hypothesis.
10 dimes cost 10 cents each so 10 x 10 is 100 coins and 5 nickels are 5 cents each so 5 x 5 is 25 and 1 penny is 1 cent so if you add 100, 25, and 1 it's 126 which is 1.26
Answer:
Step-by-step explanation:
Time = 2 hrs + 12 min (10) = 4 hrs.
Cost = 35 + 20*4
Cost = 35+80
Cost = 115
