Which of the following circumstances is likely to result in the highest stan- dard error for the mean? You may assume each of these variables is roughly normally
distributed and that samples were done responsibly. Explain why you chose the answer
you did.
1. A sample of 221 final exam scores which has a sample standard deviation of 11
points
2. A sample of 34 radio listeners about how many podcasts they listen to, in which
the sample standard deviation is 11 podcasts
3. Data collected on a sample of 221 newborn babies which showed that their gestation
lengths varied with a standard deviation of 6 days
4. A sample of 34 Emergency Room patients recording how many hours they spent in
the hospital, with a standard deviation of 6 hours

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
