Classify the following data. Indicate whether the data is qualitative or quantitative, indicate whether the data is discrete, co

ntinuous, or neither, and indicate the level of measurement for the data.
A company's international marketing group asked the following question to residents of 50 countries: "What has been your experience with American products?"
1) Below Average 2) Average 3) Above Average 4) Good to Excellent

A supervisor must give a summary evaluation rating from among the choices given below:
1) Poor 2) Fair 3) Good 4) Very good 5) Excellent

Are these data qualitativeor quantitative?
Are these data discrete or continuous?

What is the highest level of measurement the data possesses?
1) Nominal
2) Ordinal
3) Interval
4) Ratio

Answer:

The data is quantitative

Data is discrete

The highest level is Ordinal

Step-by-step explanation:

Data is of quantitative type when it allows us to measure, in a numerical and objective way, the differences  between different observations. Eventhough the supervisor uses words ( fair, poor etc) he can assign numerical values and measure differences between observations that has sense. Qualitative data refers to opinions, stories, interviews, images or data that cannot be interpreted numerically and has subjective interpretations depending in researcher.

Data is discrete because the variable measured: evaluation rating, can only takes certain specific values (1 to 5) A continuous variable, such as height can take many values in a ratio or real line,

Nominal data refers to variables that takes two possible values - the presence and absence of a characteristic, like being or not being a minor. Ordinal variables are variable which are discrete but the value of the variable allows to classify data in a specific order. This is the case of the rating scale. Interval variables are are ones that have specific low levels and high levels like age ranges.

The area of a circle is 615.44 in2. What is the diameter of the circle? Use 3.14 for π.
Shalnov [3]
615.44 = (3.14)(radius)^2 

<span>radius = square-root of (615.44/3.14) </span>

<span>diameter = radius x 2 </span>

est scores for a statistics class had a mean of 79 with a standard deviation of 4.5. Test scores for a calculus class had a mean
Arte-miy333 [17]

Answer:

The z-score for the statistics test grade is of 1.11.

The z-score for the calculus test grade is 7.3.

Due to the higher z-score, the student performed better on the calculus test relative to the other students in each class

Step-by-step explanation:

Z-score:

In a set with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

In this question:

The grade with the higher z-score is better relative to the other students in each class.

Statistics:

Mean of 79 and standard deviation of 4.5, so \mu = 79, \sigma = 4.5

Student got 84, so X = 84

The z-score is:

Z = \frac{X - \mu}{\sigma}

Z = \frac{84 - 79}{4.5}

Z = 1.11

The z-score for the statistics test grade is of 1.11.

Calculus:

Mean of 69, standard deviation of 3.7, so \mu = 69, \sigma = 3.7

Student got 96, so X = 96

The z-score is:

Z = \frac{X - \mu}{\sigma}

Z = \frac{96 - 69}{3.7}

Z = 7.3

The z-score for the calculus test grade is 7.3.

On which test did the student perform better relative to the other students in each class?

Due to the higher z-score, the student performed better on the calculus test relative to the other students in each class

Jim wants to build a rectangular parking lot along a busy street but only has 2400 feet of fencing available. if no fencing is r
PSYCHO15rus [73]
<span>Length = 1200, width = 600
   First, let's create an equation for the area based upon the length. Since we have a total of 2400 feet of fence and only need to fence three sides of the region, we can define the width based upon the length as: W = (2400 - L)/2
   And area is: A = LW
    Substitute the equation for width, giving: A = LW A = L(2400 - L)/2
    And expand: A = (2400L - L^2)/2 A = 1200L - (1/2)L^2
    Now the easiest way of solving for the maximum area is to calculate the first derivative of the expression above, and solve for where it's value is 0. But since this is supposedly a high school problem, and the expression we have is a simple quadratic equation, we can solve it without using any calculus. Let's first use the quadratic formula with A=-1/2, B=1200, and C=0 and get the 2 roots which are 0 and 2400. Then we'll pick a point midway between those two which is (0 + 2400)/2 = 1200. And that should be your answer. But let's verify that by using the value (1200+e) and expand the equation to see what happens:
   A = 1200L - (1/2)L^2
 A = 1200(1200+e) - (1/2)(1200+e)^2
 A = 1440000+1200e - (1/2)(1440000 + 2400e + e^2)
 A = 1440000+1200e - (720000 + 1200e + (1/2)e^2)
 A = 1440000+1200e - 720000 - 1200e - (1/2)e^2
 A = 720000 - (1/2)e^2
   And notice that the only e terms is -(1/2)e^2. ANY non-zero value of e will cause this term to be non-zero and negative meaning that the total area will be reduced. Therefore the value of 1200 for the length is the best possible length that will get the maximum possible area.</span>
