A researcher studied the number of nights doctors reported having too little sleep over a 5-week period. In an article describing the results of the study, the researcher reports: "The mean number of nights of too little sleep was 6.02 (SD = 2.74)." Explain these results to a person who has never had a course in statistics. The mean of 6.02 is a the number of nights doctors report having too little sleep over a 5-week period. It is figured by The standard deviation of 2.74 is a number of nights doctors report having too little sleep over a 5-week period. It is figured by finding from of The standard deviation is roughly the
A transmitter uses a carrier frequency of 1100 Hz so that the unmodulated carrier is $A_c \cos(2\pi f_c t)$. Determine both the phase and frequency deviation in Hz for the following transmitter output: $x_c(t) = \cos[2\pi(1300)t^3]$ Select one: a. $\phi(t) = -2\pi(1100)t + 2\pi(1300)t^3$; and $\frac{1}{2\pi}(\frac{d\phi}{dt}) = -1100 + 3900t^2$ b. $\phi(t) = -2\pi(1000)t + 2\pi(1200)t^3$; and $\frac{1}{2\pi}(\frac{d\phi}{dt}) = -1000 + 3600t^2$ c. $\phi(t) = 2\pi(1100)t - 2\pi(1300)t^3$; and $\frac{1}{2\pi}(\frac{d\phi}{dt}) = 1100 - 3900t^2$ d. $\phi(t) = -2\pi(1100)t + 2\pi(1300)t^3$; and $\frac{1}{2\pi}(\frac{d\phi}{dt}) = -1100 + 3900t^2$
