The radiation emission from cell phones is a concern for cell phone users. WE took a sample of 10 cell phones and got the mean radiation emission is 0.51W/kg with a standard deviation of 0.21W/kg. Use a 0.05 significance level to test the claim that cell phones have a mean radiation level that is less than 1.00 W/kg. Which test should you use to test the claim? a) Z-test b) Proportion Test c) T-test O d) Standard deviation test
