Question 10 i. Procedure: Select an answer Select an answer One variance x² procedure One mean Z procedure One proportion Z procedure One mean T procedure frequency (RF) energy The Specific Absorption Rate (SAR) for a cell phone measures the amount of radio absorbed by the user's body when using the handset. Every cell phone emits RF energy. Different phone models have different SAR measures. To receive certification from the Federal Communications Commission (FCC) for sale in the United States, the SAR level for a cell phone must be no more than 1 watts per kilogram. A sample of 23 models was tested and the average of their Specific Absorption Rates (SARS) was found to be 1.23 watts per kilogram. Assume that the population standard deviation is 0.25 watts per kilogram. Construct a 96% confidence interval for the average of the SARS for cell phones that received certification from FCC. You may also assume that the sample is from a normal population. ii. Assumptions: (select everything that applies) The number of positive and negative responses are both Normal population Population standard deviation is known Sample size is greater than 30 Simple random sample 11 Population standard deviation is unknown iii. Unknown parameter: Select an answer Select an answer u, population mean p. population proportion o², population variance <D> KIS
