Hi Mary,
I think the good old t-test is what you want:
x <- sample(1:50)
t.test(x, mu = 300)
gives:
One Sample t-test
data: x
t = -133.2, df = 49, p-value < 0.00000000000000022
alternative hypothesis: true mean is not equal to 300
95 percent confidence interval:
21.36 29.64
sample estimates:
mean of x
25.5
Best,
Henrik

I have a value
a=300
observation (x) = sample(1:50)
How to find a p-value from this. I need to show that "a" is different fom
mean(x).
Thanks
