I downloaded a new os from TI's website. So I went to install it. Everything was going fine but when it finished the computer gave a failed notice, and the calculator is frozen on the software installation screen and says "waiting to receive"...The usb recognizes my calculator but status is not detectable SO therefore I can't reinstall the os or even restore my calculator.

Normally distributed population; std dev = 280; random sample, n = 64; mean, xbar = 1200. Estimate the mean, mu, for the entire population. Develope the 95% confidence interval for the population mean, mu. a) Find corresponding z-values (95% confidence) b) find the corresponding x-values
