Answer:
CI = 29.8 ± 3.53
Critical value is z = 2.58
Step-by-step explanation:
First of all let's find margin of error. It is given by the formula;
ME = zσ/√n
We are given;
Standard deviation; σ = 3.62
Sample size; n = 7
Mean; x¯ = 29.8
Now, z-value for 99% Confidence level is 2.58
Thus;
ME = (2.58 × 3.62)/√7
ME = 3.53
CI is written as;
CI = x¯ ± ME
CI = 29.8 ± 3.53
Critical value is z = 2.58
Answer:
less
Step-by-step explanation:
5/10 is equal to one half, but 4/10 is less than one half
Slope = 1/2 :)
rise over run (rise/run)
so... 2/4 = 1/2
hope this helps!
Step-by-step explanation: Arrange the terms in ascending order: -7, -2/5, 3/9, 11/12.
