The US Department of Energy reported that 49% of homes were heated by natural gas. A random sample of
318 homes in Oregon found that 127 were heated by natural gas. Test the claim that proportion of homes
in Oregon that were heated by natural gas is different than what was reported. Use a 10% significance
level. Give answer to at least 4 decimal places.
What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.)
Но: Р
0.49
H1: p
0.49
Based on the hypotheses, compute the following:
Test Statistic = -3.233
p-value = 0.0012
Based on the above we choose to Reject the null hypothesis
v that the proportion of
The correct summary would be: There is enough evidence to support the claim
homes in Oregon that were heated by natural gas is different than what the DOE reported value of 49%.
