In the formula CL% confidence interval = x ZcL*
what is Z95% ?

In the formula for confidence interval; CI = X ± Z(s/√n)

what is Z95% ?

>> Z95% means critical z value for 95% Confidence level.

>> Z95% = 1.96

Step-by-step explanation:

The formula for confidence interval is given as;

CI = x¯ ± Z(s/√n)

Where:

x¯ is the mean

Z is the critical value for a particular %CL

s is standard deviation

n is sample size

Thus, Z95% means critical z value for 95% Confidence level.

From tables, the z-value for a confidence level of 95% is 1.96

answer: 38.47 is your answer

step-by-step explanation: hope i you and who ever sees this answer have a great rest of your day : )

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
