Solution:-
Mean = 8050, S.D = 5000
a) The least amount which is considered to be catastrophic is 19685.
p-value for the highest 1% = 1 - 0.01 = 0.99
z-score for the p-value = +2.327
By applying normal distribution:-
x = 19685
b) The probability that a loan default will be atleast $6000 is 0.659
x = 6000
By applying normal distribution:-
z = -0.41
P(z > - 0.41) = 0.659

Let us assume that the variable Total_Rooms follows the normal distribution with mean 87 and standard deviation 95.1. Then: 4.1 Compute the probability that a randomly selected hotel has more than 100 rooms. 4.2 Compute the probability that a randomly selected hotel has between 60 and 80 rooms. 4.3 Find what is the minimum number of rooms a hotel should have in order to be considered in the 20% of the largest in size?

summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
