2. Medical records indicate that the distribution of weights of healthy newborn babies born inthe US has mean $\mu = 6.9$ pounds and $\sigma = 0.4$ pounds. A medical doctor is interested in determining whether the mean weight of healthy newbornbabies in his network of hospitals is different than the national mean weight (6.9 pounds). He collects a simple random sample of 36 newborn babies' weights and finds the mean weight is $\bar{x} = 6.81$ pounds. a) Does this sample provide sufficient evidence at the $\alpha = 0.05$ level to suggest that the mean weight of newborn babies in this hospital network is different than 6.9 pounds? b) Is 6.9 pounds included in the 95% confidence interval for $\mu$? Is this consistent with the decision made above?

Texts: A 3-phase VRSM has the following per-phase parameters: Ra = 2Ω, La = 50mH, and a rated current of 5A. a. Determine the time constants for the turn-on and turn-off intervals of each phase. (4.16ms, 2.94ms) b. Find the corresponding supply voltage. (60V) c. If the phase current is conducted for an interval of 3(τon + τoff), determine the corresponding stepping rate (in steps per second) of the motor. (47 steps/s) Solve to get what's between brackets.
