## Homework Statement

Given ##X_1,\dots,X_{100}##, test ##H_0: \lambda=1## against ##H_a: \lambda=4##. The mean ##\bar{X_{100}}=1.5##

(1) Take the decision on 3% level.

(2) Find the p-value

## Homework Equations

##t=\frac{\bar{x}-\mu}{s/\sqrt{n}}##

## The Attempt at a Solution

The level of significance is ##0.033##. The p-value I need to evaluate ##\frac{\bar{x}-\mu}{s/\sqrt{n}}##, but I am missing ##s##. Is it still possible to have a solution?
