Answer:
A university was interested in examining the overall effectiveness of its online statistics course, along with the effectiveness of particular aspects of the course. First, the university wanted to see whether the online course was better than a standard course. Second, the university wanted to know whether students learned best using Excel, using RStudio, or using no statistical package at all. The university randomly selected a group of 30 students and administered one of the different variants of the course (i.e., traditional or online, coupled with one of the software options) to each student. The success of each variant was measured by the students' average improvement between a pre-test and a post-test. How many treatment groups are there in this study?
Option D is correct - There are 6 treatment groups in this study.
Step-by-step explanation:
The number of treatment groups is equal to the number of possible combinations of the values of the factors.
In the question given, we have two factors: type of instruction (traditional/online) and software (Excel/Minitab/none).
Since there are 2 values for 'type of instruction' and 3 values for 'software'. Hence the number of treatment groups = 2*3 = 6.
Answer:
The answer is D: 5
Step-by-step explanation:
-Online course,
-Program to use,
- Number of students,
-Administered variant,
-Measurement of the average student.

Answer:
account balance at graduation is 674.17
Step-by-step explanation:
given data
deposit money P = 500
interest rate = 3 % compounded quarterly
we take time period = 10 year ( 2nd grade to 12 grade)
solution
we apply here compound interest formula that is
amount = ..................1
put here value and we get
amount =
amount = 674.174
so account balance at graduation is 674.17
Answer:
$694.63
Step-by-step explanation:
The formula is p(1+r/n)^tn. P, or the principal amount, is 500 dollars. R, or the rate as a decimal, is 0.03. N, or the number of times compounded yearly, is 4. T, or the time in years, is 11, since there are 11 years from grade 2 to grade 12. 12-2+1=11. Now, plug in the information given. 500(1+0.03/4)^4*11 = 500(1.0075)^44 = 694.63 dollars, rounded to the nearest cent.
