Question
A market study for a new industrial product indicates that the product should be launched
by the firm only if the mean number of units purchased per customer in the first solicitation
of the firm's customers is more than 2.0. Initial orders for the product are to be solicited
from a random sample of 100 of the firm's many customers and the sample mean is
computed as 2.2. The standard deviation of the numbers of units purchased in initial orders
is assumed to be 1.6 units.
Answer the following questions according to the text above.
1- Choose the relevant hypotheses.
Ho:
2- Compute the test statistic.
3- if the significance level is 0.05, what is the decision rule for the test.
(Note that; za means z, or ta(df)
means t(df) )
4- State your decision and conclusion at a significance level of 0.05.
5- Calculate the p-value for the test.
