Answer:

Statistical Questions: 1 and 3

NOT Statistical Questions: 2 and 4

Step-by-step explanation:

A statistical question is one that can be answered by collecting data and where there will be variability in that data. This is different from a question that anticipates a deterministic answer.

For example, "How many minutes do 6th grade students typically spend on homework each week?" is a statistical question.

A dashboard warning light is supposed to flash red if a car’s oil pressure is too low. On a certain model, the probability of th

PilotLPTM [1.2K]

Answer:

0.8462 or 84.62%

Step-by-step explanation:

The probability that the light flashes is given by the probability of it flashing when it should added to the probability of flashing when it should not:

$P(F) = P(O)*P(F_O)+P(N)*P(F_N)\\P(F) =0.10*0.99 + (1-0.10)*0.02\\P(F) = 0.117$

The probability that the oil pressure is low (driver needs to be concerned) is given by the probability that oil is low and the light flashes divided by the probability that the light flashes.

$P(O|F) =\frac{P(O_F)*P(O)}{P(F)} \\P(O|F) =\frac{0.99*0.10}{0.117}\\ P(O|F) =0.8462$

When the warning light goes on, there is a 0.8462 probability that the oil pressure is low.
