The distribution of the number of transactions per day at a certain automated teller machine (ATM) is
approximately normal with a mean of 80 transactions and a standard deviation of 10 transactions. Which of
the following represents the parameters of the distribution?
ī=80; s = 10
B
I = 80; 92 = 10
I = 80; o = 10
D x = 80; o = 10
Ei=80; 8 = 10

Answer:

ī=80; s = 10

Step-by-step explanation:

When the standard deviation is from a finite group it is denoted by s. The number of transactions from an atm are countable in a day. So the standard deviation will be represented by s.

and ī represents the mean.

The other choices are incorrect because mean is usually represented by a bar over the alphabet such as x.

a simple alphabet does not denote the mean of the sample or population.

Parameters are the characteristics used to define a dataset.

The representation of the parameters are: [tex]\bar x = 80[/tex] and  [tex]s = 10[/tex]

From the question, we have:

[tex]Mean = 80[/tex]

[tex]Standard\ Deviation = 10[/tex]

Mean is represented as: [tex]\bar x[/tex]

So, we have:

[tex]\bar x = 80[/tex]

Standard deviation is represented as [tex]\sigma[/tex] of s.

So, we have:

[tex]s = 10[/tex]

Hence, the representation of the parameters are:

[tex]\bar x = 80[/tex] and  [tex]s = 10[/tex]
