Answer:
1.
: p = 0.70 ,
: p > 0.70
2. Test Statistic : 0.54 , P value : 0.2946
3. Fail to reject null Hypothesis
4. No.
Step-by-step explanation:
1. Null hypothesis is 70% of children receive antibiotics.
Alternative hypothesis is more than 70% of children receive antibiotics.
2. Test statistic is calculated as;
z = 
z = 
z = 0.54
3. p value is calculated as;
1 - right tailed probability
1 - 0.7054 = 0.2946
Answer:
system A because we can substitute y in 2nd equation into the first equation
also system B because we can substitute x in the 1st equation into 2nd equation
