Answer:
0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine
Step-by-step explanation:
(a) What is the probability that a randomly chosen doctor is in favor of the vaccine
75% of 115/250 = 0.46(German).

65% of 70/250 = 0.28(Englishmen). So

0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine
Answer:
We reject the null hypothesis.
Step-by-step explanation:
We are given the following information in the question:
Sample size, n = 71
Population variance is known.
Level of significance, α = 0.08

The null and alternate hypothesis are:

We use one-tailed z test to perform this hypothesis.
Formula:

Now, 
Since,

We fail to accept the null hypothesis and reject it and accept the alternate hypothesis.
