(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 sample mean and its standard error. (c) (d) Calculate an equal-tailed 50% confidence interval for 0.
