-77
Step-by-step explanation:
-77 + -23 = -100
2.73972603 or ... you can round to the nearest tenth... 2.7
2y^2 = x^2
y = x/sqrt(2)
how?
y = (x^2)/(2y)
y(2y) = (x^2)(2y)/(2y)
The sample mean of the random sample is 50
The margin of error (E) is the amount of error allowed in the random sample.
The confidence interval (CI) is given by:
CI = μ ± E = (μ - E, μ + E)
Given a confidence interval of (38.02, 61.98), hence:
μ - E = 38.02 (1)
μ + E = 61.98 (2)
Hence solving equations 1 and 2 simultaneously gives:
μ = 50, E = 11.98
Hence the sample mean of the random sample is 50
