![A simple experiment with a random sample of 10 mathematics students were
found to have the following heights (in cm).
155, 185, 175, 175, 173, 170, 169, 164, 161, 185
Assume the heights of mathematics students are independently and normally
distributed X ~ N(0,0²) with a known variance of o² =99.12 cm².
(a)
Calculate a point estimate of the mean height 0 and a probability that this
estimate is exactly equals to the true value of 0.
(b)
Compute the standard error, ơ/\n of the sample mean by using given
variance.
Estimate an equal-tailed 90% confidence interval for 0 by using the
