10000000
Because 10 to the 7th power means multiply 10 by itself 7 times.
It's either 0.354249 or 5.645751 I hope this helped. (Btw both are correct I just simplified them from 3+<span>√7 and </span>3−<span>√<span>7)</span></span>
Answer:
The 85% confidence interval for the true mean number of reproductions per hour for the virus is between 10.1 and 10.3.
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 10.2 - 0.1 = 10.1 reproductions per hour.
The upper end of the interval is the sample mean added to M. So it is 10.2 + 0.1 = 10.3 reproductions per hour.
The 85% confidence interval for the true mean number of reproductions per hour for the virus is between 10.1 and 10.3.
Answer:
I guess the answer is 5 and 8
