Suppose the average Canadian household spends $1,800a year on all types of insurance. Suppose the figures are uniformly distributed between the values of $300and $3,300.

*(Round your answer to 1 decimal place, e.g. 1.7.) **(Round your answers to 6 decimal places, e.g. 0.759634.) ***(Round your answers to 4 decimal places, e.g. 0.7574.)

(a) What are the standard deviation of this distribution?

Standard deviation = *

(b) What are the height of this distribution?

Height = **

(c) What proportion of households spends more than $3,000a year on insurance?

P(x >3,000) = ***

(d) What proportion of households spends more than $3,500a year on insurance?

P(x >3,500) = ***

(e) What proportion of households spends between $500and $1,400a year on insurance?

P(500< x <1,400) = ***
