Answer the questions please

7- What is the minimum sample size needed when doing population means if the margin of error you want is E = 8.5 grams and the sample standard deviation is s = 68.5 grams? 8. 106 adults are randomly selected and tested for their body temperatures. Based on that sample, it is estimated that the average (mean) body temperature is 98.2 degrees Fahrenheit with a margin of error of 0.1 degrees Fahrenheit. a. What 1is the population? b. What is the sample statistic? c. What 1s the population parameter? 9. In a survey of 703 randomly selected workers, 429 got their jobs through networking.
