<h2><u>
x=−3/7</u></h2>
Step-by-step explanation:
Let's solve your equation step-by-step.
34x=27x−3
Step 1: Subtract 27x from both sides.
34x−27x=27x−3−27x
7x=−3
Step 2: Divide both sides by 7.
7x\7=−3\7
x=−3/7

Answer:
The minimum sample size required to construct a 95% confidence interval for the population mean is 65.
Step-by-step explanation:
We are given the following in the question:
Population standard deviation,
We need to construct a 95% confidence interval such that the estimate is within 0.75 milligrams of the population mean.
Thus, the margin of error must me 0.75
Formula for margin of error:
Putting values, we get,
Thus, the minimum sample size required to construct a 95% confidence interval for the population mean is 65.
