Answer:
d. 0.0948 ± 4.032(0.0279)
Step-by-step explanation:
A 99% confidence interval for the coefficient of promotional expenditures is, First, compute the t critical value then find confidence interval. 
The t critical value for the 99% confidence interval is,  
The sample size is small and two-tailed test. Look in the column headed es = 0.01 and the row headed in the t distribution table by using degree of freedom is here 
for (n-2=5) degree of freedom and 99% confidence ; critical t =4.032
therefore 99% confidence interval for the slope =estimated slope -/+ t*Std error
= 0.094781123 -/+ 4.032* 0.027926367 = -0.017822 to 0.207384

Answer:
B
Explanation: 
Theoretical probability is a method to express the likelihood that something will occur. It is calculated by dividing the number of favorable outcomes by the total possible outcomes.
The empirical probability, relative frequency, or experimental probability of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space but in an actual experiment.
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
I'm not showing you all of them, but this one is very simple.
You convert the percent(25%) to a decimal(0.25), then multiply it by the whole number(24). So simple, I got it all in one sentence.
0.25x24=6
25% of 24 is 6.
