For random samples of size 100 from a population, the mean of the sample means from all possible samples is <u>less than</u> the population means.
The suggestion of the pattern means will equal the population suggest. the standard deviation of the distribution of the sample means, called the same old blunders of the suggested, is the same as the population trendy deviation divided by means of the rectangular root of the sample length (n).
The general sample suggests components for calculating the pattern mean.
The populace suggest is the mean or average of all values within the given population and is calculated by using the sum of all values within the population denoted with the aid of the summation of X divided by way of the number of values in the population that's denoted with the aid of N.

Answer:
<u>I will take around 1 year and 8 months to earn $ 45 of interest on this investment</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Interest earned = $ 45
Investment = $ 790
Annual simple interest rate = 3.4% = 0.034
2. How much time would it take to earn $45?
Let's recall the formula for calculating the simple interest of an investment:
A = P * (1 + rt)
Replacing with the values we already have:
835 = 790 + (1 + 0.034t).
Where t is the time we want to calculate
835 = 790 + 26.86t
26.86t = 835 - 790
26.86t = 45
t = 1.68 (Rounding to the next hundredth)
<u>t ≅ 1 year and 8 months</u>
About 6.6088 (rounded to the nearest thousandth)
