Answer: a) (176.76,172.24), b) 0.976.
Step-by-step explanation:
Since we have given that
Mean height = 174.5 cm
Standard deviation = 6.9 cm
n = 50
we need to find the 98% confidence interval.
So, z = 2.326
(a) Construct a 98% confidence interval for the mean height of all college students.
(b) What can we assert with 98% confidence about the possible size of our error if we estimate the mean height of all college students to be 174.5 centime- ters?
Error would be
Hence, a) (176.76,172.24), b) 0.976.
35,030,000 is the correct answer, hope this helps.
To write 0.1 as a percentage you have to multiply it by 100 and then put the % sign at the end of it.
0.1 X 100 = 10%
Answer: 5
example:
4-2=2+8=10/2
=(2)
The definition of a prime number is one in which there are no factors other than 1 and itself. For example, 5 has no other factors other than 1 and 5 (itself).
The number 1 is not considered prime nor composite.So, even though it is a square (1²), it is not a prime number.
All square numbers have a square root that is neither 1 nor itself: 16 is the square of 4, 49 the square of 7, and so on.
Due to the fact that square numbers have factors other than 1 and itself, square numbers are not prime.
Hope this helps! :)
