A medical researcher says that less than 87​% of adults in a certain country think that healthy children should be required to be vaccinated. In a random sample of 500 adults in that​ country, 85​% think that healthy children should be required to be vaccinated. At alphaequals0.05​, is there enough evidence to support the​ researcher's claim? Complete parts​ (a) through​ (e) below.

It is not enough evidence to support the researcher's claim.

Step-by-step explanation:

Since we have given that

n = 500

So, the hypothesis are as follows:

So, the z value would be

At α = 0.05

z= -1.64

So, 1.64<-1.33

So, we accept the null hypothesis.

Hence, it is not enough evidence to support the researcher's claim.

total = principal × ( 1 + rate ) ^ years

total = 600 * (1.04)^5

total = 729.99

answer is c
