Answer:
We want to find the percentage of values between 147700 and 152300
And one way to solve this is use a formula called z score in order to find the number of deviations from the mean for the limits given:
And replacing we got:
So then we are within 1 deviation from the mean so then we can conclude that the percentage of values between $147,700 and $152,300 is 68%
Step-by-step explanation:
We define the random variable representing the prices of a certain model as X and the distirbution for this random variable is given by:
The empirical rule states that within one deviation from the mean we have 68% of the data, within 2 deviations from the mean we have 95% and within 3 deviations 99.7 % of the data.

Answer and explanation :
Hannah said that is not on the number line but she is wrong because
can be represented on the number line
When we convert the fraction into decimal then it is equal to 0.125
And 0.125 lies between 0 and 1
If we divide one unit on number line into 10 parts then 0.125 lie between 0.1 and 0.2
And we know that any real number can be represented on number line as 0.125 is a real number so it can be represented on the number line
