10. Medical records at a doctor's office reveal that 12% of adult patients have seasonal
allergies. Select a random sample of 100 adult patients and let y = the number of
individuals in the sample who have allergies.

a) Calculate the mean and standard deviation of the sampling distribution of Y.

b) Interpret the standard deviation from part (a)

c) Would it be appropriate to use a normal distribution to model the sampling distribution of
Y? Justify your answer.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
