Suppose certain electronic components require gold leaf to produce - say with standard deviation o = 19 cm? and unknown mean. We want to test, in an unbiased way, whether the mean amount of gold leaf required per component is 22 cm', and are given the information that for a particular sample of size 73 (supposed to be independent and identically distributed) we have sample mean 28 cm? Give appropriate null and alternative hypotheses for this problem. In cm?, the null hypothesis is Ho : / while the alternative hypothesis is H1 : u Calculator Overview standard function logic . vector abc unit W P O 14.C Clear ~ 8 0 (fro
