Image transcription text
Suppose certain electronic components require gold leaf to produce - say with standard deviation
" = 19 cm' and unknown mean. We want to test 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
Given the above information (plus Ho, H1. the observed test statistic z and the P-value from the last
three exercises), state your conclusion at the a - 0.05 level of significance. Tick ALL statements that
are correct.
We reject Ho
O .We do not reject Ho
Evidence suggests the true value of the mean amount of gold leaf required per component
is not 22 .
We do not have enough evidence to believe the mean amount of gold leaf required per
component is not 22
0
The mean amount of gold leaf required per component is not 22
The mean amount of gold leaf required per component is 22
