A manufacturer claims that a particular automobile mannequin will get 50 miles per gallon on the freeway. The researchers at a consumer-oriented journal imagine that this declare is excessive and plan a check with a easy random pattern of 30 vehicles. Assuming the usual deviation between particular person vehicles is 2.three miles per gallon, what ought to the researchers conclude if the pattern imply is 49 miles per gallon?The P-value of .0087 is enough proof to reject the manufacturer’s declare.There may be not enough proof to reject the manufacturer’s declare; 49 miles per gallon is near the claimed 50 miles per gallon.The manufacturer’s declare must be rejected as a result of the pattern imply is lower than the claimed imply.The manufacturer’s declare shouldn’t be rejected as a result of the P-value is simply too small.The P-value of .0087 is enough proof to show that the manufacturer’s declare was a lie.
