Mrs. Voorhees claims that a Bowie knife is the most effective method of disposing rowdy campers. In a random sample of campers at Lake Crystal, a statistician found that a 99% confidence interval for the proportion of campers disposed by a Bowie knife is 0.7326 to 0.8154. A study claims that the proportion of campers disposed by a Bowie knife is 78%. What can we conclude if we use the above confidence interval to test the claim? A.Since 0.78 does not fall in the confidence interval, evidence indicates the study’s claim is correct. B.Since 0.78 falls in the confidence interval, evidence indicates the study’s claim is incorrect. C.Since 0.78 does not fall in the confidence interval, evidence indicates the study’s claim is incorrect. D.Since 0.78 falls in the confidence interval, evidence indicates the study’s claim is correct.

Question

Mrs. Voorhees claims that a Bowie knife is the most effective method of disposing rowdy campers. In a random sample of campers at Lake Crystal, a statistician found that a 99% confidence interval for the proportion of campers disposed by a Bowie knife is 0.7326 to 0.8154.

A study claims that the proportion of campers disposed by a Bowie knife is 78%. What can we conclude if we use the above confidence interval to test the claim?

Since 0.78 does not fall in the confidence interval, evidence indicates the study’s claim is correct.

Since 0.78 falls in the confidence interval, evidence indicates the study’s claim is incorrect.

Since 0.78 does not fall in the confidence interval, evidence indicates the study’s claim is incorrect.

Since 0.78 falls in the confidence interval, evidence indicates the study’s claim is correct.
