Question:

A Scientist wishes to test the impact of four synthetic specialists on the time span of usability of a specific assortment of tomato. The tomatoes are conveyed in boxes, and one expects critical timeframe of realistic usability inconstancy between boxes. Recognize the exploratory units, reaction variable, factor(s), levels of each factor, and the quantity of medicines in this investigation. What kind of exploratory plan ought to be utilized? In the event that 24 examples of every treatment will be taken, yet each case just supplies 12 tomatoes, at that point how might the investigation be planned to kill the impact of box inconstancy?

Of all understudies at the University of Metropolis, the extents taking certain quantities of units are as demonstrated in the table beneath.

\16\

Units 3 4 5 6 7 8

Proportion 2% 4% 5% 7% 5% 4%

Units 9 10 11 12 13 14

Proportion 8% 11% 13% 13% 16% 12%

Track down the normal number of units that an understudy at U.M. takes. (Enter your response to two decimal spots.)

MTN Ghana wishes to get clients' perspectives on their fulfillment with the help they have gotten. The organization chooses to review guests who phone its call-focus, to acquire their perspectives. Clarify how you would utilize deliberate examining to choose an example of 100 guests over a six-day time frame from Monday to Saturday on the off chance that you realize that the rough number of calls is 400 every day. Disclose how to diminish inclination during the testing interaction by giving two explicit models

A PC lab in a school has 33 PCs. Every one of the 33 PCs has 90% unwavering quality. Taking into account 10% of the PCs to be down, a teacher

determines an enlistment roof of 30 for his group. Expect that a class of 30 understudies is

taken into the lab.

a. What is the likelihood that every one of the 30 understudies will get a PC in

working condition?

b. The educator is astonished to see the low estimation of the response to (a) and

chooses to improve it to at any rate 95% by doing one of the accompanying:

I. Diminishing the enlistment roof.

ii. Expanding the quantity of PCs in the lab.

iii. Expanding the dependability of the relative multitude of PC

How do you interpret a statistically significant univariate chi-square? Include formulae if needed. (5 marks) C. Describe how you determine the expected values for a bivariate chi-square test? (2 marks) d. How do you interpret a statistically significant bivariate chi-square? Include formulae if needed. (5 marks) e. Is the McNemar test a univariate or a bivariate chi-square analysis? (2 marks) Why? (2 marks) f. How do you determine the expected values for a McNemar test? (2 marks) Why are the expected values derived in this way? (3 marks) g. How is a statistically significant McNemar test interpreted? Include formulae if needed. (5 marks)QUESTION 1 True or False: The blocking variable in randomized complete block design is always a random effects variable. True False QUESTION 2 True or false: Graeco-Latin square designs can be for any p greater than or equal to 3. True FalseIA. The study of economics is comprised of three general areas: microeconomics, macroeconomics, and econometrics. What is econometrics? Provide a comprehensive definition of econometrics. IB. What are the two general uses of econometric models? List and briefly discuss both of these. IC. The multiple linear regression model was argued, in general, to be superior to the uni-variate linear regression model for two reasons. Considering your response to IB, discuss the two reasons the multiple regression model is superior.Click Submit to complete this assessment.
