Answer:
standard error = 1.63
Step-by-step explanation:
To calculate the standard error we need to know the standard deviation (σ) and the sample size (n) (see the attached formula).
To obtain the standard deviation we use the given sample variance of 77.4 years:
σ²= variance
Therefore:
σ = √77.4 = 8.8
Now we can calcuate the estimated standard error:
standard error = σ /√n = 8.8/√29 = 1.63
The standard error gives us an estimation about how far the mean of the sample is from the mean of the entire population, and in this case is 1.63.
1*106=106
5*10-5=495
495/106≈ 4.67
Answer:
$45
Step-by-step explanation:
Let the regular price be x
according to the question
the equation is
x×85/100=38.25
x×85/100=38.25
x=38.25×100/85
x=38.25×20/17
x=45
