Drug Ifal data - Use the Happy 1 variable. Suppose someone claims the population mean 15 53 and the standard deviation is 10. Quality Control (potato chip) Data - Use the Weight variable. Suppose someone claims the population mean is 2.4, and the standard deviation is 0.55. Sales Employee Evaluation Data - Use the July#Sales variable. Suppose someone claims the population mean is 23, and the standard deviation is 4.5. PART 1 - Sampling Distribution Exercises For now, assume both of the claims about the population are correct. la. Given the assumed pop. mean and st.dev, calculate the probability of observing a value above the number for your first data point in your file. 1b. Suppose you collected 8 new data points in a new sample. Calculate the probability that the mean of these 8 new data points is above the number for your first data point in your file. 1c. If this is a normally distributed variable, above what value should you find 70% of data f tha this
