Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
![39. Reconsider the accompanying sample data on expense
ratio (%) for large-cap growth mutual funds first intro-
duced in Exercise 1.53.
0.52 1.06 1.26 2.17 1.55 0.99 1.10 1.07 1.81 2.05
0.91 0.79 1.39 0.62 1.52 1.02 1.10 1.78 1.01 1.15
A normal probability plot shows a reasonably linear
Pattern
a. Is there compelling evidence for concluding that the
population mean expense ratio exceeds 1%? Carry out
a test of the relevant hypotheses using a significance
level of .01
b. Referring back to (a), describe in context type I
and Il errors and say which error you might have
made in reaching your conclusion. The source
from which the data was obtained reported that
µ = 1.33 for the population of all 762 such funds.
So did you actually commit an error in reaching
your conclusion?
c. Supporting that o = 05, determine and interpret the
power of the test in (a) for each actual value of u
stated in (b).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd7d679a1-84c3-4bb8-9ae6-a66cd12a1e51%2F5b91d942-da51-47ec-95a4-a6b75d0c8b78%2Fypgb0xr_processed.png&w=3840&q=75)
