Answer:
And we can conclude that the true mean for the heights of mens between the ages of 18 to 24 is between 69.44 and 69.7 inches.
Step-by-step explanation:
For this case we have the following sample size n =772 from men recruits between the ages of 18 to 24
represent the sample mean for the heigth
represent the population standard deviation
We want to construct a confidence interval for the true mean and we can use the following formula:
The confidence level is 0.99 or 99%o then the significance level is and and if we find for a critical value in the normal tandar ddistirbution who accumulates 0.005 of the area on each tail we got:
And replacing we got:
And we can conclude that the true mean for the heights of mens between the ages of 18 to 24 is between 69.44 and 69.7 inches.
Answer:
Burning fossil fuels and driving cars
Step-by-step explanation:
For this case we must find the domain of the following function:
By definition, the domain of a function is given by all the values for which the function is defined. The given function is not defined when the denominator is zero, that is:
Thus, the domain of the function is given by real numbers except 2.
Answer:
All real numbers except 2
Answer:
(-3,5)
Step-by-step explanation:
so if you go to the point you look down to see where it hits the x axis at so when you do that, you will hit -3 on the x axis, now go to the point again then go across the y axis to where the point would be if you went over, it will hit at 5 on the y-axis. hope thats a good enough description
pls mark the brainliest also hope that helps!!
