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:
No, the two ratios are not the same.
Step-by-step explanation:
When we are saying "apples to oranges", mathematically it means:
,
Which could be 2:3 or 3:2, which in fractional from are written as 
and 
respectively.
We see that
In words the ratio 2:3 says "for every two apples there are three oranges", and 3:2 says "for every three apples there are two oranges". Again we see that the two sentences are not saying the same thing, therefore the ratio 2:3 is not same as 3:2.
