Answer:
(a) P-value = 0.001
Conclusion: The average reflectometer reading for the new type of paint under consideration is greater than 20.
(b) P-value = 0.036
Conclusion: The average reflectometer reading for the new paint under consideration is 20
Step-by-step explanation:
The test is a one-tailed test because the alternate hypothesis is expressed using greater than.
(a) n = 16, t = 3.3, a = 0.05
Cumulative area of the test statistic t is 0.9995
P-value = 1 - 0.9995 = 0.0005 = 0.001 (to 3 decimal place)
Conclusion:
Reject H0 because the P-value 0.001 is less than the significance level 0.05.
(b) n = 8, t = 1.8, a = 0.01
Cumulative area of the test statistic t is 0.9641
P-value = 1 - 0.9641 = 0.0359 = 0.036 (to 3 decimal places)
Conclusion:
Fail to reject H0 because the P-value 0.036 is greater than the significance level 0.01
Answer:
9.6miles per hour
Step-by-step explanation:
2/3＝40min
32/5 /40＝0.16
0.16miles per min
0.16*60＝9.6
Answer:
<h2>1986, 1996</h2>
Step-by-step explanation:
Given, Annual passenger revenue for the years 1980 to 2000 id=s modeled with the formula 
.
Here, 
is the annual revenue in millions of dollars, 
is the number of years since January 1, 1980.
Revenue in a year was $ 790 million.
So, 
So, after 6 yrs and 16 yrs from January 1, 1980, the Passenger revenue equals $ 790 million.
∴ Passenger revenue equals $ 790 million in 1986 and 1996.
