The value is
Step-by-step explanation:
From the question we are told that
The mean of Jo cows is
The standard deviation of Jo cow is
The mean of Val cows is
The standard deviation of Val cows is
The sample size for both Val and Jo is n = 25
Let assume that the level of significance is
Generally from the normal distribution table the critical value of is
Generally the margin of error is mathematically represented as
Hence margin of error for Jo is

Answer:
197.9
Step-by-step explanation:
The formula for circumference is 2(pi)r and r is the radius
The diameter is two times the size of the radius, so by dividing the diameter by two, you can get the radius
So, r=63/2
r= 31.5
That means that 2(pi)(31.5) is the circumference
2(pi)(31.5) = 197.9 (rounded to the nearest tenth)
