Science Alert reports that giant pandas weigh less than an average of 4.6 ounces at birth.

In order to verify the results of the report, a simple random sample of 13 giant pandas are selected and it is determined that the average weight at birth is 4.2ounces with a standard deviation of .83 ounces.Determine if there is enough evidence to support the claim made by Science Alert at a 10% level of significance.Use the rejection region method.Assume that the birth weights of giant pandas are normally distributed.
