Data collected by the NCHS shows the percentage of adults told they have hypertension;is 23.53 percent. If we select a simple random sample of 20 US adults and assume the;probability that each has been told they have hypertension is.24.;This survey also shows that 32 percent indicated that they have been tested for HIV.;Consider a simple random sample of 15 adults selected at that time. Find the probability;that the number of adults who have been tested for HIV in the sample would be;a.;b.;c.;d.;e.;Three;Less than 5;Between 5 and 9, inclusive;More than 5 but less than 10;6 or more;2. An investigator looked at the occurrence of RCH, a benign retinal tumor, in people with;von Hippel-Lindau disease.(VHL) The researchers found the number of RCH tumor;incidents followed a Poisson distribution with = 4 tumors per eye with patients with;VHL. Using this model, find the probability that in a randomly selected patient with VHL;a.;b.;c.;d.;There are exactly 5 occurrences of tumors per eye;There are more than 5 occurrences of tumors per eye;There are fewer than 5 occurrences of tumors per eye;There are between 5 and 7 occurrences of tumors per eye, inclusive;3. Calculate the following both;Manually AND;Using SPSS show SPSS printout;For a subject (29 year old male) in a study, acetone levels were normally distributed with;a mean of 870 and a standard deviation of 211 ppb. Find the probability that on a given;day the subjects acetone level is;a.;b.;c.;d.;1;Between 600 and 1000 ppb;OVER 900 ppb;Under 500 ppb;Between 900 and 1100 ppb;4. Consider the following on serum Cholesterol levels of males.;Age 25-34 (X);Population mean;Population standard deviation;Age 20 24 (Y);= 180;= 49;Sample size;= 199;= 43;n=50;a). Compute the probability that the difference in mean;m=50;of two groups is greater;than 22.;b). Compute the probability that the difference in mean;18 and 21.;2;of two groups is between
