Question: Let r1 and r2 be the signal strengths received by a mobile from base stations 1 and 2, respectively. The probability distribution of r1 and r2 are:
p(r1)=0.1, p(r2)=0.1, 0≤r1,r2≤10;
Assume r1 and r2 are independent random variables. When the mobiles are near the cell border, they can have adequate communication with more than one base station if r1/r2 <2 and r2/r1 <2. What is the probability that the mobile can have adequate communication with both base stations?
The received signal of a communication system r = s + N . Here, s is source information and takes the value of 1 or -1. N is the noise uniformly distributed in the interval of [-x +x].

A 15-minute Oil and Lube service claims that their average service time is no more than 15 minutes. A random sample of 35 service times was collected, and the sample mean was found to be 16.2 minutes, with a sample standard deviation of 3.5 minute..
At the 10% level of significance, does the following sample evidence indicate that the two population means are equal? Assume the populations are normally distributed.
