Last summer I collected data from my students and it turned out that their average height was 67” with standard deviation 4.0”. There were 58 students in class that day. I want to know if my students are, on average,taller than I am? I am 64” tall.

1. we are testing

2. H_0:

_3. H_a:

4. We will do a z-procedure because the sample size is large.

5. If the population mean __________ is indeed __________, then due to sampling variation alone __________ of all possible sample mean __________ are expected to be ________________________________________, when the samples consist of __________ ____________________ each.

Assume that I asked heights of 40 female students. It turns out that average height and standard deviation of ladies in our class is 164 cm and 9 cm, respectively. For all computations, assume that the heights follow a normal distribution. For hypothesis test questions please use 5 step procedure. a. (CI) Find a 95% confidence interval for the height of the female students. b. (CI) Without making any computation, can you test whether ?=163 or not at ?=0.05? Why?...

I was listening to my radio one night and I noticed that when I turned on my desk light there was a little blip of noise on the radio. I repeated this and I noticed that when I was on the border of completing the circuit, such that when the bulb was flickering, I got severe interference on my radio. My radio was running on batteries. Why does this happen?
