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

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!

Answer:
The amount of increase per hour by $1.
Step-by-step explanation:
Julian charges $10 for every hour he walks a dog.
He increases his fee by 10%
Now we have to find 10% of $10
Amount increased =
So the amount increased by $1.
The amount of increase per hour by $1.
