Suppose the null hypothesis, h0, is: a weightlifting bar can withstand weights of 800 pounds and less. what is the type i error in this scenario?

Type I error α is the probability of rejecting the null hypothesis when the null hypothesis is actually true.

In the case of this problem, the type I error would be rejecting the null hypothesis, therefore, thinking that the weightlifting bar cannot withstand weights of 800 pounds and less, when it actually can.

a.   mass number from atomic number

i think the answer is a, hope this : )
