Answer:18
Step-by-step explanation:
18
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.
Answer:
47/12, or 3 11/12
Step-by-step explanation:
9 1/2 - 5 7/12 > convert to improper fractions
19/2 - 67/12
make same denominator (12)
19/2 * 6 = 114/12
114/12 - 67/12 = 47/12
Answer:
a
Step-by-step explanation:
Write the total number of seeds in scientific notation
Given:
Number of pots = 22,000
Number of seeds = 15
<em>Total number of seeds = Number of pots × Number of seeds</em>
= 22,000 × 15
= 330,000
Scientific notation is written in multiples of 10
- Count the number of digits
- Insert a decimal point between the first digit and other digits
- count the number of digits after the first digits
- multiply by 10 raise to the power of number of remaining digits after first digits
= 3.30000 × 10^5
Therefore,
the total number of seeds in
scientific notation is 3.30000 × 10^5
