Claim: The proportion of brown M&Ms more than 22%. A simple random sample of 150 M&Ms contains 26% brown.
\n" ); document.write( "I have to identify the null and alternative hypothesis and identify the sampling distribution (normal, t, chi-square) of the test statistic or state that none of the sampling distributions would work.
\n" ); document.write( "------
\n" ); document.write( "Ho: p <= 0.22
\n" ); document.write( "Ha: p > 0.22
\n" ); document.write( "----------
\n" ); document.write( "test statistic: z(0.26) = (0.26-0.22)/sqrt[0.22*0.78/150] = 1.1826
\n" ); document.write( "Distribution: Normal
