Solution:-
a) Since p-value is greater than 0.05, there is no significant interaction.
State the hypotheses. The first step is to state the null hypothesis and an alternative hypothesis.
Null hypothesis: There is no interaction between gender and age.
Alternative hypothesis: There is interaction between gender and age.
Formulate an analysis plan. For this analysis, the significance level is 0.05.
Analyze sample data.
F statistics is given by:-
F = 0.148
Fcritical = 3.56
The P-value = 0.86
Interpret results. Since the P-value (0.86) is greater than the significance level (0.05), we have to accept the null hypothesis.
Conclusion:-
Do not reject H0, There is no interaction between gender and age.
b) (B) Since p-value for gender is small, rates are affected by gender.
State the hypotheses. The first step is to state the null hypothesis and an alternative hypothesis.
Null hypothesis: u1 = u2
Alternative hypothesis: At-least one of the u is not equal.
Formulate an analysis plan. For this analysis, the significance level is 0.05.
Analyze sample data.
F statistics is given by:-
F = 5.36
Fcritical = 4.41
The P-value = 0.033
Interpret results. Since the P-value (0.033) is less than the significance level (0.05), we have to reject the null hypothesis.
Conclusion:-
Reject H0, There is sufficient evidence for significant differences between the genders.
c) (A) Since p-value for age is small, rates are affected by age.
State the hypotheses. The first step is to state the null hypothesis and an alternative hypothesis.
Null hypothesis: u1 = u2 = u3 = u4
Alternative hypothesis: At-least one of the u is not equal.
Formulate an analysis plan. For this analysis, the significance level is 0.05.
Analyze sample data.
F statistics is given by:-
F = 5.06
Fcritical = 3.56
The P-value = 0.018
Interpret results. Since the P-value (0.018) is less than the significance level (0.05), we have to reject the null hypothesis.
Conclusion:-
Reject H0, There is sufficient evidence for significant differences between the age groups.

so i have my c++ code and ive been working on this for hours but i cant get it to run im not allowed to use arrays. im not sure how to fix it thank you for the help our job is to write a menu driven program that can convert to display Morse Code ere is the menu the program should display Menu Alphabet Initials N-Numbers - Punctuations S = User Sentence Q- Quit Enter command the user chooses...
okay so here is my c++ code and the errors im really stuck on fixing what i did wrong it seems to be the same repeated error our job is to write a menu driven program that can convert to display Morse Code ere is the menu the program should display Menu Alphabet Initials N-Numbers - Punctuations S = User Sentence Q- Quit Enter command the user chooses A your program should use a loop and your morse code printing...
As you know from Project 4, McCormick & Company is considering building a new factory in Largo, Maryland. McCormick & Company decided to offer $4,424,000 to obtain the land for this project. The new factory will require an initial investment of $350 million to build the new plant and purchase equipment. You have been asked to continue your work from project 4 with a full analysis of the proposed factory, including the start-up costs, the projected net cash flows from...
