Answer:
The 90% confidence interval for the true mean number of reproductions per hour for the bacteria is between 11.2 and 11.6 reproductions.
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 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 11.4 - 0.2 = 11.2 reproductions.
The upper end of the interval is the sample mean added to M. So it is 11.4 + 0.2 = 11.6 reproductions.
The 90% confidence interval for the true mean number of reproductions per hour for the bacteria is between 11.2 and 11.6 reproductions.
Answer:
m<1 = 121°
m<2 = 59°
Step-by-step explanation:
If m<1 is the supplement of m<2 and the measure of each angle is given:
m<1=2x+65
m<2=3x-25
Find m<1:
When two angles are supplement of each other, there sum is equal to 180°
i.e m<1 + m<2 = 180°
Putting values and finding angle 1
So, we get x=28
Now finding m<1 by putting x=28
Now, finding m<2 by putting x=28
So, we get:
m<1 = 121°
m<2 = 59°
