13) The time spent for studying for the maths (X) is exponentially distributed with
Mean = 
= 4.2 hours
So, the parameter of the exponential distribution will be -
P(3 < X < 5) = P(X < 5) - P(X < 3) 
= 0.6988- 0.5132
= 0.1856
Hence, the option (c) is the correct option.
14) Appropriate hypothesis are -
Ho : 
Ha : 
Hence, option (c) is the correct option.
Usually what we wish to know is kept in alternative hypothesis, here we wishe to test whether prices in Cupertino was greater than country average (683,008)
