1.Data were collected over a 10-year timespan from a sample of 100 penguins that were randomly given either metal or electronic tags. One variable examined is the survival rate 10 years after tagging. The scientists observed that 10 of the 50 metal tagged penguins survived, compared to 18 of the 50 electronic tagged penguins.

State hypotheses in terms of the parameters given to test whether the survival rate is lower among metal-tagged penguins than among electronic-tagged penguins.

a.Use Normal distribution methods to calculate a z-test statistic, given SE = 0.090.

Find the p-value and draw a Normal curve with appropriate shaded region.
