1. The normal proportion of basophil granulocytes is 0.5 for one hundred leucocytes.
What is the probability to not find any among 200 leucocytes observed under these
conditions? (2 points)
2. There are an average 10 cases of disease D in a given region over a year. We suppose that the probability of a person living in this region has this disease is low. Calculate the probability that (strictly) less than three people will have this disease
during the year. (2 points)
3. We are interested in a blood test in children of less than 15 years of age for which the distribution in the studied population follows a normal distribution of mean  = 22 and variance  2 = 34. In the population what is the proportion of children:
- for whom the test result is higher than 25? (1.5 points)
- for whom the test result is lower than 12? (1.5 points)
4. We want to describe the users (age and sex) of anxiolytics drugs in the French population and the duration of treatment use in the French population. For this study, we have selected a representative sample of the French population. Using the data contained in table 1 and table 2, answer to the following questions:
a. In France, we know that the mean of duration of treatment of anxiolytics use is 12 months (variance=20.5). How many mean of duration of treatment do we expect to find in our sample (with a risk of 5%)? (2 points)
b. In France, we know that the percentage of female is 52%. How many female do we expect to find in our sample (with a risk of 5%)? (2 points)
c. We want now estimate with a risk of 1% the mean duration of treatment in our sample (give a point estimate and its interval) (2.5 points)
d. We want estimate with a risk of 10% the mean of age in our sample (give a point estimate and its interval) (2.5 points)
e. We want estimate with a risk of 5% the frequency of female in our sample (give a point estimate and its interval) (2 points)
f. If the mean of age is 40 years old (variance=10.3) and if we want built a confidence interval with a risk of 5% and precision of 10%, which size of sample have you we need? (2 points)

If u spend more time on your books than you spend online daily u will realize how easy this ur statistics assignment is.
Go study hard instead of running here to ask for "expo"!!

Wld ve loved to help out but that is not my field!
Dnt even understand a jack there, wish some of these e-warrious will do humanity good for once by helping u out here.
