Answer: 126
Step-by-step explanation:
As per given , we have
Prior Population proportion : 
Significance level : 
Critical value for 95% confidence interval (using the z-value table) = 
Margin of error (maximum error): 
Formula to find the sample size :
Therefore , the required minimum sample size = 126
I think the correct answer from the choices listed above is the second option. Solving a 6 order system <span>would be the process that is used to describe solving a system of equation with 6 variables. The number of variables should be equal to the order of the system for it to be solved. Hope this answers the question.</span>

Answer:
The observed tumor counts for the two populations of mice are:
Type A mice = 10 * 12 = 120 counts
Type B mice = 13 * 12 = 156 counts
Step-by-step explanation:
Since type B mice are related to type A mice and given that type A mice have tumor counts that are approximately Poisson-distributed with a mean of 12, we can then assume that the mean of type A mice tumor count rate is equal to the mean of type B mice tumor count rate.
This is because the Poisson distribution can be used to approximate the the mean and variance of unknown data (type B mice count rate) using known data (type A mice tumor count rate). And the Poisson distribution gives the probability of an occurrence within a specified time interval.
