From past harvests, the population standard deviation was observed to be 8 mangoes. Find the point and the interval estimates of the population mean µ per kaing, using 98% confidence. Step 1: The parameter of interest is the mean u of the population where the sample comes from. Step 2: The sample information consists of raw scores n = and o = , The sample size of 50 kaing is large enough for the Central Limit Theorem to satisfy the assumption that the sampling distribution of means is normally distributed. The z-test is also applicable. Step 3: The level of confidence is or a = Critical z values:_ This means that if more random samples are taken from the target population and an interval estimate is made for each sample, then 95% of the intervals ill contain the true parameter value.
