What is the probability of rolling the number 4 (on one die) and the number 3 (on the other die) with a normal pair of dice if you roll the dice 100 times?

Statistics > Hypothesis Testing
In 1980, the Gallup poll asked Americans whether current safety regulations made nuclear power plants safe enough. Of the 420 respondents ages 18 to 30, 24% answered "yes." Of the 510 respondents ages 30 to 50, 34% answered "yes."
1. Calculate the p-value for H (age makes no difference.)
* I don't know how to find the std. deviation or the population mean value for the equation
Z = (sample mean - population mean)/(std. deviation/Square root of population sample) Help Please!! Thanks.

Probability of Success = 1/6*1/6 + 1/6*1/6 = 1/18 ( if I roll once)

So if I roll ...

  • Statistics Null Hypothesis Rejection

    Now, since p = 0.217, we simply need to calculate the chance of f(0) + f(1) + f(2).............f(47), where f(k) = C(200, k) 0.217^k 0.783^(200 - k) This is = 0.7616 Binomial probability distribution Probability of not rejecting a false null hypothesis
