You perform 7000 significance tests using a significance level of 3%. assuming that the null hypothesis is true, how many of the test results would you expect to be statistically significant?

210

Step-by-step explanation:

we have given significance level α=3% =0.03

level of significance is nothing but the chances of rejecting a null hypothesis by the test when it given that it is correct. it is denoted by α it also defined as the

level of significance =1 - confidence level

now statistically significant test =0.03×7000=210

so the expected value of statistical significant is 210

i have no idea just need points sorry

step-by-step explanation:

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
