Step-by-step explanation:
4(c+2)<4c+10
4c+8<4c+10
-4c -4c
--------------------
8<10
Which gives you No Solution.
The answer is: " 4.58 * 10⁻² " .

Answer: One sample z test for means
Step-by-step explanation:
From the information given, the sample size is large. It is greater than 30. Again, the population standard deviation is given. This means that the test statistic would be the z score which is determined by the formula
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
The probability value would be determined from the normal distribution table.
Therefore, the hypothesis test that should be used is
One sample z test for means
