Please only answer if you know your answer is correct! I've wasted several questions because people give me the wrong answers!! Thanks

The null and alternate hypotheses are:

H0: μ1 ≤ μ2

H1: μ1 > μ2

A random sample of 25 items from the first population showed a mean of 106 and a standard deviation of 12. A sample of 15 items for the second population showed a mean of 104 and a standard deviation of 6. Use the 0.10 significant level.

a) Compute the value of the test statistic.

Answer #1

a)
t = (x1-x2)/sqrt(s1^2/n1+s2^2/n2)
= (106 - 104)/sqrt(12^2/25+ 6^2/15)
= 0.7001


p value = .2477

Do not reject H0

    Commercial real estate prices and rental rates suffered substantial declines in 2008 and 2009.† These declines were particularly severe in Asia; annual lease rates in Tokyo, Hong Kong, and Singapore declined by 40% or more. Even with such large declines, annual lease rates in Asia were still higher than those in many cities in Europe. Annual lease rates for a sample of 30 commercial properties in an Asian city showed a mean of $1,120 per square meter with a standard...
