which tree diagram shows all the possible outcomes when a number cube with sides labeled 1-6 is rolled then a coin is flipped

The null hypothesis is not rejected  and hence Type II error occurred

Step-by-step explanation:

Here

The null hypothesis is as follows

H0 = Mean = 0.5

The alternate hypothesis is as follows -

H1 = Mean >0.5

For Type I error = The Null hypothesis is rejected if null hypothesis is actually true

Type II error =The Null hypothesis is not rejected when the null hypothesis is not true but is false.  

Here, the null hypothesis is not rejected  and hence Type II error occurred
