196

Step-by-step explanation:

Given that the significance level of 2% = α

Because the the null hypothesis is true so it is denoted by α it also defined as the level of significance = 1 - confidence level = 1 - 0.02 = 0.98.

So the number of the tests will incorrectly find significance:

=0.98*200=196
