...How many standard deviations is my hypothesis (sample mean) is away from the actual (null hypothesis population mean)
T – statistic
Rejecting the null may be a mistake = p –value
ONE SAMPLE
3 formulas
T.Dist.rt (t, sample size - 1 “df”) -> alternative that mu is bigger than a
1 – T.Dist.rt (t, sample size – 1) -> mu is less than a
T.Dist.2t(t,samplesize - 1) -> not equal to
p < significant level reject the null
NEVER accept null
TWO SAMPLE

...PART I. HYPOTHESIS TESTING
PROBLEM 1 A certain brand of fluorescent light tube was advertised as having an effective
life span before burning out of 4000 hours. A random sample of 84 bulbs was burned out
with a mean illumination life span of 1870 hours and with a sample standard deviation of 90
hours. Construct a 95 confidence interval based on this sample and be sure to
interpret this interval.
Answer
Since population standard deviation is unknown, t distribution can be used...
