14/60 is your answer which can be reduce to 7/30
The distance between C and A/D is 1,2 km. The distance between B and A/C is 0,6. It's in this order: A 0,6 km B 0,6 km C 1,2km D so the distance between B and D is 0,6 + 1,2 = 1,8 km
Answer:
Fail to reject the null hypothesis.
Step-by-step explanation:
The hypothesis test is conducted for Boston public school. They have used z-value table and the value of test statistics is 1.20. AT the significance level of 0.05, the null hypothesis is accepted. We cannot reject the null hypothesis. The p-value is greater than alpha so there is no evidence to support the claim of Boston Public School.
All in all, we are selecting from a pool of 17 members (4+9+4 = 17). So seeing we have 4 democrats, the probability would be 4/17.
Normally we would simplify the fraction from there but 4/17 is already the simplified form. Therefore that is already the answer.
