Answer:
(3-x) is the other factor.
Step-by-step explanation:
The given function is :
One of the factor is (x-4)
We need to find the other factor.
It can be solved as follows :
So, the other factor is (3-x).

Answer:
Step-by-step explanation:
Given that:
Mean = 3.34
sample size = 26
sample mean = 2.7
standard deviation = 1.17
level of significance = 0.10
The null hypothesis and the alternative hypothesis can be computed as follows:
degree of freedom = n - 1
degree of freedom = 26 -1
degree of freedom = 25
level of significance = 0.10
Since the alternative hypothesis contains <, then the test is left tailed
= - 1.316
The rejection region therefore consist of all values smaller than - 1.316, therefore ; reject if t < -1.316
The test statistics can be computed as follows:
t = - 2.789
Decision Rule: To reject the null hypothesis if the t test lies in the rejection region or less than the rejection region.
Conclusion: We reject the null hypothesis since t = (- 2.789) < -1.316. Then we conclude that the mean number of residents in the retirement community household is less than 3.34 persons.
