The salary in 2012 was $65,000.
If the inflation rate is 4%, the salary should increase at least 4% per year to keep up with inflation.
Then, we can calculate the salary adjusted by inflation in 2021 as:
Replacing with the data, we get:
Answer: the adjusted salary to keep up with inflation should be $92,515.27 in 2021.
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!
