There is insufficient information to answer the question.
None of these
3. The length of time that it takes the tollbooth attendant to service each driver can typically be described by the
normal distribution.
uniform distribution.
exponential distribution.
Poisson distribution.
None of these
4. Data for a particular subdivision near downtown Houston indicate that the average price per square foot for a home is $100 with a standard deviation of $5 (normally distributed). What is the probability that the average price per square foot for a home is greater than $90?
0
0.023
0.159
0.977
None of these
5. What makes the difference between good decisions and bad decisions?
A good decision is based on logic.
A good decision considers all available data.
A good decision considers all alternatives.
A good decision applies quantitative approaches.
All of these
6. Which of the following statements is false concerning the hypothesis testing procedure for a regression model?
The F-test statistic is used.
The null hypothesis is that the true slope coefficient is equal to zero.
The null hypothesis is rejected if the adjusted r2 is above the critical value.
An level must be selected.
The alternative hypothesis is that the true slope coefficient is not equal to zero.
