The equation for QR is 5y = -42 +41. Is QR tangent to Circle O at R?
No, because the slope of OR times the slope of QR
does not equal -1.
YA
R(4,5)
Yes, because the slope of OR times the slope of
QR equals 1.
No, because the slope of OR times the slope of QR
does not equal 1.

Arandom sample of n = 25 observations is taken from a n(µ, σ ) population. a 95% confidence interval for µ was calculated to be (42.16, 57.84). the researcher feels that this interval is too wide. you want to reduce the interval to a width at most 12 units. a) for a confidence level of 95%, calculate the smallest sample size needed. b) for a sample size fixed at n = 25, calculate the largest confidence level 100(1 − α)% needed.
