Ответ:
70
Step-by-step explanation:
I suppose its 70 because... 7 + 3 = 10
and 70 + 30 = 100...so the SUM is 100...yet minus 30 would be 70...so
70 is the bigger number...
please let me know if this was right...
hope I helped!

We do not reject the null hypothesis.
Step-by-step explanation:
When the p-value is greater than the significance level , then we do not reject the null hypothesis or if p-value is smaller than the significance level , then we reject the null hypothesis.Given : Test statistic :
Significance level :
By using the standard normal distribution table ,
The p-value corresponds to the given test statistic ( two tailed ):-
Since the p-value is greater than the significance level of 0.02.
Then , we do not reject the null hypothesis.
