The following are questions from a self-quiz. according to some study, the height for northern european adult males is normally distributed with an average of 181 centimeter and a standard deviation of 7.3 centimeter. suppose such an adult male is randomly chosen. let x be height of that person. the next 2 questions correspond to this information. the answer may be rounded up to 3 decimal places of the actual value. a) the probability that the person is between 160 and 170 centimeters isb) the probability that the person is higher than 190 centimeter is

a) 0.064

b) 0.109

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 181 centimeter

Standard Deviation, σ = 7.3 centimeter

We are given that the distribution of height for Northern European adult males is a bell shaped distribution that is a normal distribution.

Formula:

a) P(person is between 160 and 170 centimeters)

b) P(person is higher than 190 centimeter)

P(x > 190)

Calculation the value from standard normal z table, we have,  

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

i think it is c, not positive though

step-by-step explanation:
