(5pts) What requirements are necessary for a normal probability distribution to be a standard normal probability distribution? a) The mean and standard deviation have the values of -1 and -1 b) The mean and standard deviation have the values of 1 and c) The mean and standard deviation have the values of 0 and 1 d) The mean and standard deviation have the values of 0 and = 0 2. (8pts) Find the area of the shaded region. The graph depicts the standard normal distribution of bone density scores with mean 0 and standard deviation 1 Z-0.88 z-1.24 The area of the shaded region is 3. (20 pts) A survey found that women's heights are normally distributed with mean 62.5 in. and standard deviation 2.9 in. The survey also found that men's heights are normally distributed with a mean 67.3 in' and standard deviation 2.8 in Complete parts (a) through (c) below a) Most of the life characters at an amusement park have height requirements with a minimum of 4ft 3 in. and a maximum of 6ft 6in. Find the percentage of women meeting the height requirements. Round to four decimal places. The percentage of women that meet the requirements is

Explanation / Answer

Answer- Standard normal distibution is the normal distribution with mean = 0 and standard deviation = 1

We have to find P( -0.88 < Z < 1.24)

= P(Z<1.24) - P(Z<-0.88)

= 0.8925 - 0.1894 [ using normal tables ]

= 0.7031
