A random sample of 30 children from this age group was? selected, with a sample average of 8.4 hours of electronic media use per day. Complete parts a and b below.
a. Is there support for the claim of the study using the criteria that the sample average of 8.4 hours falls within the symmetrical interval that includes? 95% of the sample means if the true population mean is 7.4 ?hours? Select the correct choice below and fill in the answer box within your choice.
A.The probability Px≥8.4=. This indicates that the sample average of 8.4 hours falls within the? 95% symmetrical? interval, supporting the claim of the study.
B.The probability Px≥8.4= . This indicates that the sample average of 8.4 hours falls outside the? 95% symmetrical? interval, contradicting the claim of the study.
