Assume that when shopping for a Nintendo Switch, the probability of finding the Switch at any given store is .25. We’ll assume that this is modeled by a binomial distribution that uses the formula:

P(x successes in n trials) = nCx · p x · (1 − p) n−x Assuming that n = 9 people go shopping for the Switch,

(a) what is the probability that 3 people will find the switch?

(b) what is the probability that at least 2 people will find the Switch?

(c) what is the expected number (µ) of the 9 people that can find the Switch when going shopping?

7. Which of the following is true when finding the probability based on – sampling distribution? A. Normality is given by BOTH the population being normal and n ≥ 30 B. Normality is given by BOTH np ≥ 5 and nq ≥ 5. C. We have to either add or subtract .5 to the x-value to make our answer more accurate. D. To find the standard error of the mean we take the population standard deviation and divide by the...

A circuit has a 2.9 V battery connected in series with a switch. When the switch is closed, the battery powers two paths in parallel, one of which has a resistor of resistance R1 = 80 Ω in series with an inductor of inductance L = 1×10−2 H , while the other has a resistor of resistance R2 = 230 Ω . What is the current supplied by the battery at a time t = 0.25 ms after the switch...
