A local greenhouse sells coffee-tree saplings. They price their saplings based on the height of the plant. They have two workers, Susan and Karen, who measure the saplings for pricing. The greenhouse manager wants to determine if there is a significant difference in the measurements made by these two individuals. She has them measure the same set of 15 saplings. Assume that the differences are calculated as Susan – Karen.
Use this information to answer questions 5, 6, and 7.
Question 5
Select all of the correct null and alternative hypotheses.
Select one or more:
H0: μd=0
H0: μd=15
H0: μd=0
H0: μd≠0
HA: μd≠0
HA: μd≠15
HA: μd<15
HA: μd>15
The greenhouse manager wants to determine if there is a significant difference in the measurements made by these two individuals. Hence,
Our hypotheses will be:
H0: μd = 0
HA: μd ≠ 0
Option C and Option E are correct.

Two proposed computer mouse designs were compared by recording wrist extension in degrees for 24 people who each used both mouse designs.† The difference in wrist extension was calculated by subtracting extension for mouse type B from the wrist extension for mouse type A for each person. The mean difference was reported to be 8.82 degrees. Assume that this sample of 24 people is representative of the population of computer users. (a) Suppose that the standard deviation of the differences...

Local government is worried that runoff from a corporate farm has caused water in a nearby stream to become acidic. The pH is used to measure the acidity/alkalinity of a substance. Pure water, for instance, has a pH of 7, and smaller pH values indicate acidity, while larger values indicate alkalinity. A contractor is hired to test the hypothesis that the water is significantly acidic. Use this information to answer questions 3 and 4. 3) Select the correct null and...
A bioengineering firm was working to increase the yield of eggplant crops, and it developed two promising strains of eggplant. In early tests, Strain A appeared to produce a slightly smaller yield than Strain B, but the difference was too small to be significant. The company decided to check that Strain A produced less than Strain B by replicating the test on a much larger scale by planting the crops in 15 different fields. The fields were randomly assigned a...
Suppose that you are given a data set which predicts the price of coffee based on loss of forest in Indonesia. Software tells us that the least-squares slope from 10 different observations is b = 0.54 with standard error SEb = 0.1. Please use 2 decimal places. What is the t statistic for testing H0: ? = 0? How many degrees of freedom does t have? Use a t-table to approximate the P-value of t against the one-sided alternative Ha:...
