Answer:
Answer is 12-19 = -7
Step-by-step explanation:
12- 19 you can break 19 into 12 +7
then
it is easy to find 12-12 = 0
Now subtracts 0 - 7 =- 7
then
break 7 into 3 + 4

12 - 19 = -7
Answer:
you<u> accept </u>the alternative hypothesis
Step-by-step explanation:
The null and alternative hypothesis can be computed as follows:
The sample proportion
The test statistics can be computed as:
Z = -2.5
The P-value = 2( Z< -2.5)
From the tables;
The P-value = 2 (0.0062)
The P-value = 0.0124
The significance level = 0.01
Since the P-value is > significance level; we fail to reject the null hypothesis.
Conclusion: we accept the alternative hypothesis
