Suppose that lithium calculator battery with a charge of 3 volts, actually has a voltage with uniform distribution between 2.93 and 3.1 volts. What are the expected voltage and standard deviation of voltage? What is the probability that a battery has a voltage less than 2.98?
a. E(X) = 2.413, STDEV(X)= 0.0024, P (X ≤ 2.98) = 0.3342
b. E(X) = 3.015, STDEV(X)= 0.049, P (X ≤ 2.98) = 0.2941
c. E(X) = 3.015, STDEV(X)= 0.0049, P (X ≤ 2.98) = 0.1041
d. None of the preceding
e. E(X) = 3.015, STDEV(X)= 0.0024; P (X ≤ 2.98) = 0.2941
f. E(X) = 2.413, STDEV(X)= 0.049, P (X ≤ 2.98) = 0.2941
