Answer:
The 95% confidence interval of the mean time it took a person to find their dream home is between 5.64 months and 6.16 months.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 5.9 - 0.26 = 5.64 months
The upper end of the interval is the sample mean added to M. So it is 5.9 + 0.26 = 6.16 months.
The 95% confidence interval of the mean time it took a person to find their dream home is between 5.64 months and 6.16 months.
Answer:
100
Step-by-step explanation:
Hello! to calculate the number of tiles needed for the floor you need two things
1. number of tiles that fit across the width, this is achieved by dividing the total width by the width of each tile
Width=20ft=240in
2.number of tiles that fit in the logitude, this is achieved by dividing the total length by the length of each tile.
leght=30ft=360in
Finally, you multiply the number of tiles that fit in width by the number of tiles that fit in length.
N=10X10=100
