Step-by-step explanation:
Answer:
it is not necessary to confirm that the sample data appear to be from a population with a normal distribution;
D. Because the sample size of 50 is greater than 30, it can be assumed that the sample mean is from a population with a normal distribution
Step-by-step explanation:
Normal distribution which is otherwise known as the Gaussian distribution, it is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.
The arithmetic mean or average; is the sum of a collection of numbers divided by the total numbers in the collection.
Given:
The table of values of an exponential function.
To find:
The decay factor of the exponential function.
Solution:
The general form of an exponential function is:
...(i)
Where, a is the initial value and 
is the decay factor and 
is the growth factor.
The exponential function passes through the point (0,6). Substituting 
in (i), we get
The exponential function passes through the point (1,2). Substituting 
in (i), we get
Here, 
lies between 0 and 1. Therefore, the decay factor of the given exponential function is 
.
Hence, the correct option is A.
