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
