Use a: = 0.01. 1. The population distribution requirement for this test is: '33:? Need a normally distributed population since 'n 59000 O Ho: / 2 59000; Ha: / 59000 2. This is a O right two left tailed test and the distribution used is O T since o not known O Z since o known O Z since testing a proportion The Degrees of Freedom are ON/A; this is a Z-test O 39 O 40 3. The STS (round to 3 decimals) is: The P-value (round to 4 decimals) is:4. The decision at a: = 0.01 is: '3' Do not reject Ho since P 31 a '3' Do not reject Ho since P > or '3' Reject Ho since P 3'. a '31:?
