It is claimed that 75% of puppies are house-trained by the time they are 6 months old. To investigate this claim, a random sample of 50 puppies is selected. It is discovered that 42 are house-trained by the time they are 6 months old. A trainer would like to know if the data provide convincing evidence that greater than 75% of puppies are house-trained by the time they are 6 months old. The standardized test statistic is z = 1.47 and the P-value is 0.0708. What conclusion should be made using the Alpha = 0.05 significance level? Because the P-value is greater than Alpha = 0.05, there is convincing evidence that 75% of puppies are house-trained by the time they are 6 months old.
Because the P-value is greater than Alpha = 0.05, there is not convincing evidence that 75% of puppies are house-trained by the time they are 6 months old.
Because the P-value is greater than Alpha = 0.05, there is convincing evidence that greater than 75% of puppies are house-trained by the time they are 6 months old.
Because the P-value is greater than Alpha = 0.05, there is not convincing evidence that greater than 75% of puppies are house-trained by the time they are 6 months old.
