Answer:
The interval from the sample of size 400 will be approximately <u>One -half as wide</u> as the interval from the sample of size 100
Step-by-step explanation:
From the question we are told the confidence level is 95% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of is
Generally the 95% confidence interval is dependent on the value of the margin of error at a constant sample mean or sample proportion
Generally the margin of error is mathematically represented as
Here assume that is constant so
=>
=>
So let and
=>
=>
=>
So From this we see that the confidence interval for a sample size of 400 will be half that with a sample size of 100
Answer:
Scale of the Map = 1 cm to 82 Km
Step-by-step explanation:
25cm is equivalent to 2050Km
Hence 1cm will be equivalent to 2050/25 = 82Km
