Step-by-step explanation:
To find how many MORE miles you could've driven on the highway, we first need to find the number of miles on the highway is compared to 123 miles in the city.
Let x = number of miles in the highway
x = 157.44
So now that we know the value of x, we then subtract it to the number of miles in the city to find how much MORE you could've driven.
Total Miles = 157.44 - 123
Total Miles = 34.44
Answer: Yes, this suggest that the actual percentage of type A donations differs from 40%, the percentage of the population having type A blood.
Step-by-step explanation:
Since we have given n = 157
x = 86
So,
and we have p = 0.4
So, hypothesis would be
Since there is 1% level of significance.
So, test statistic value would be
and the critical value at 1% level of significance , z = 2.58
Since 2.58<3.846.
So, we reject the null hypothesis.
Hence, Yes, this suggest that the actual percentage of type A donations differs from 40%, the percentage of the population having type A blood.
