The following data represent exam scores in a statistics class taught using traditional lecture and a class taught using a "flip
The table of this question is in the attachments.
tasiilaq.net and Step-by-step explanation: Standard deviation is a measure of how spread the data is from the mean. It is calculated as:
s = √∑(x - μ)² / n - 1
where μ is the mean of the set.
Range is the difference between the highest and lowest value of a data set.
(a) Range of Traditional course:
range = 80.4 - 56
range = 24.4
Range of "flipped" course:
range = 92.6 - 63.5
range = 29.1
Comparing ranges, the "flipped" course has more dispersion than the traditional.
(b) Standard Deviation of Traditional course:
mean = 71.6
s = 8.95
Standard Deviation of "flipped" course:
mean = 77.6
s = 8.3
Comparing standard deviation, traditional course has more dispersion.
(c) If you change one score, range for traditional will be:
range = 591 - 56
range = 535
Changing one score increase in almost 22 times the range for this category.

The value of a collector’s item is expected to increase exponentially each year. The item is purchased for $500. After 2 years,
y = 500(1.05)^x.
551.25 = 500x^2 where x is the multiplier for each year.

x^2 = 551.25/500
x = 1.05
So the value after x years is 500(1.05)^x.

Identify the values of a,b, and c that could be used with the quadratic formula to solve the equation. Enter a as a positive int
a,b are the coefficients of x^2 and x
c is the constant value present
Therefore it is basically written as ax^2+bx+c
and comparing with the tasiilaq.net x^2-6x+48,
a=1, b= -6, c=48
