To solve this problem, plug 8250 in for b and 15 in for t and then solve for k:
<em>*Divide both sides by 1000*</em>
<em>*Take the natural log (ln) of both sides*</em>
2.1102=15k
<em>*Divide both sides by 15*</em>
0.1406=k
0.1406 rounds to 0.141 which is close to a. 0.143.
Hope this helps!!
Answer:
We also know that we select a sample size of n =100 and on this case since the sample size is higher than 30 we can apply the central limit theorem and the distribution for the sample mean would be given by:
And the standard deviation for the sampling distribution would be:
So then the answer is TRUE
Step-by-step explanation:
Let X the random variable of interest and we know that the true mean and deviation for this case are given by:
