Two different types of drugs A and B were tried on different patients for increasing weight. 5 persons were given A and 7 persons were given B. Increase in weights(in. kg) are given below:
A: 3.6 5.5 5.9 4.1 1.4
B: 4.5 3.6 5.5 6.8 2.7 3.6 5.0
Do the drugs differ significantly with regard to their effect in increasing weight?
----- This question is from the Test of Hypothesis -----
A: 3.6 5.5 5.9 4.1 1.4
B: 4.5 3.6 5.5 6.8 2.7 3.6 5.0

= 0,otherwise
Calculate the value of Z?
= 0,otherwise
Calculate the value of Z?

The mean serum-creatinine level measured in 12 patients 24 hours after they received a
newly proposed antibiotic was 1.2 mg/dL. If the mean and standard deviation of serum
creatinine in the general population are 1.0 and 0.4 mg/dL, respectively, then, using a
significance level of .05, test whether the mean serum-creatinine level in this group is
different from that of the general population.

In a city, the daily consumption of Electric power in millions of ‘kwh’ can be considered as a random variable following Gamma Distribution with α= 3, λ= ½. If the power plant in that city has a daily consumption of 12 million KWs, what is the probability that this supply of power is ‘insufficient’ in any given day?[ Hint: Find P(X>12)]

The brain volumes (cm3) of 20 brains have a mean of 1161.2cm3 and a standard deviation of122.7 . Use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such data, would a brain volume of 1446.6 be significantly high?
