D. think about it this way. the closer it is to decimal, the closer it is to a whole number which is the "biggest"
Answer:
9 and -5
Step-by-step explanation:
9*-5=-45
9+-5=4
25/7
You multiply 3 and 7 which gives you 21. Add 4 to 21, giving you 25. The improper fraction would be 25/7
Answer:
Because z is higher than any given value in the chart we come to the conclusion To reject null hypothesis
Step-by-step explanation:
Sample proportion = p= 531/648 = 0.8194
This is the proportion of men that were hit by lightening
Null hypothesis: H0: p = 0.5
Alternate hypothesis: H1: p ≠ 0.5
Test statistics z = 0.8194-0.5/(√0.5x0.5/648)
= 0.8194-0.5/√0.0003858
= 0.3194/0.019642
= 16.26
Since the z > 1.96 (at 5% significance) we reject the null hypothesis.
Therefore in conclusion we say z is higher than given values in the chart so we reject null hypothesis.
