Inferential statistics
Explanation:
Descriptive statistics describes data and gives us a picture of what the data summary looks like using such things as mean and central tendency measures. Inferential statistics on the other hand aims to make predictions using the data based on data analysis such as collecting sample from population and constructing hypotheses to estimate outcomes for the general population. Example in the question, the first is inferential statistics as we make generalized predictions on batteries using data samples from the population of batteries of a particular type.

Answer:
Therefore after 16.26 unit of time, both accounts have same balance.
The both account have $8,834.43.
Explanation:
Formula for continuous compounding :
P(t)= value after t time
= Initial principal
r= rate of interest annually
t=length of time.
Given that, someone invested $5,000 at an interest 3.5% and another one invested $5,250 at an interest 3.2% .
Let after t year the both accounts have same balance.
For the first case,
P= $5,000, r=3.5%=0.035
For the second case,
P= $5,250, r=3.5%=0.032
According to the problem,
Taking ln both sides
Therefore after 16.26 unit of time, both accounts have same balance.
The account balance on that time is
=$8,834.43
The both account have $8,834.43.
