Does the frequency distribution appear to have a normal distribution using a strict interpretation of the relevant criteria?Tem
perature(f)35-39,40-44,45-49,50-54
Frequency 3,0,4,15
Temperature(f)55-59,60-64,65-69
Frequency 7,5,1
Does the frequency distribution appear to have a normal distribution?
A. All these requirements are met
B.no, this distribution does not appear to be normal
C. No frequencies do not decrease from the maximum frequency to a low frequencies
Frequency 3,0,4,15

1 answer:
Answer:
B. No, this distribution does not appear to be normal
Step-by-step explanation:
Hello!
To observe what shape the data takes, it is best to make a graph. For me, the best type of graph is a histogram.
The first step to take is to calculate the classmark`for each of the given temperature intervals. Each class mark will be the midpoint of each bar.
As you can see in the graphic (2nd attachment) there are no values of frequency for the interval [40-44] and the rest of the data show asymmetry skewed to the left. Just because one of the intervals doesn't have an observed frequency is enough to say that these values do not meet the requirements to have a normal distribution.
The answer is B.
I hope it helps!

Important information:
Circumference of a circle=
Method:
To work out the diameter, we would need to divide the circumference of 34.54 by pi, which in this case is 3.14, this gives us 11cm. This is because we are simply rearanging the formula of the circumference of a circle to make the diameter the subject.
Step By Step:
1) Rearange the formula to make the diameter the subject.
2) Divide 34.54 by 3.14().
The right answer is -2/3

Answer:
r = 5 inches
Step-by-step explanation:
Area of circle,
It is required to find the radius of the circle. The area of a circle is given by the formula :
r is radius of the circle
So, the radius of the circle is 5 inches.
