V A signal is transmitted with intensity u. The intensity recorded at Station A varies due to noise added to the signal. The noise is known to be normally distributed with mean 0 and variance 9. Ten independent recorded intensities are: 17, 21, 20, 18, 19, 22, 20, 21, 16, 19 1. Use this data to find a 95% confidence interval for u 2. How many intensity readings would be needed to get a 95% confidence interval of length less than 1? 3. Test the hypothesis u = 20 at the .05 level. Include p-value. 4. Using the above data, compute a 95% confidence interval for the variance.
