    Question Hypothesis Problem = 50% Right

    hy,

    my friend has said to me that i can conduct a hypothesis test with the Z distibution (normal distribution) at the 3% significance level as you can look up 0.97 in the percentage points of the normal distirubtion tables to be your critical value. but i said to him that i could only do it with 10%, 5%, and 1%

    who is correct?

    thanks

    You can use whatever level of significance you want. The critical value of z is easily found from tables or technology.
