Q1) Burning rates of 2 different solid-fuel propellants utilized in aircrew escape systems are being studied. It is known that both propellants have about same standard deviation of burning rate, that is σ1=σ2=3 centimeters per second. 2 random samples of n1=20 and n2=20 specimens are tested, sample mean burning rates are x bar 1=18 centimeters per second and x-bar2=24 centimeters per second.
a) Test hypothesis that both propellants have same mean burning rate. Utilize α=0.05. Compute the P value.
b) Create a 95% confidence interval on difference in means μ1-μ2. Determine the practical meaning of this interval.

Suppose that an IQ test was given to a large group of persons, the scores are assumed to be from a normally distributed population, that mean = 100 and s (standard deviation) = 15.
In 1965, a newspaper carried a story about a high school student who reported getting 9207 heads and 8743 tails in 17,950 coin tosses. Is this a significant discrepancy from the null hypothesis H 0 = 1/2.
