P(z = 0.56) = 0.2877
P(z = 0.99) = 0.1611
P(z = 1.04) = 0.1492
P(z= -0.99) = 0.8389
Hence z = 0.99
Correct option is B
The value of z is 0.99

A sample of call duration between different UPRM students is found to be 1.01, 0.97, 1.03, 1.04, 0.99, 0.98, 0.99, 1.01, and 1.03 minutes. Calculate a 99% confidence interval for the mean call duration (minutes), assuming an approximately normal distribution. Select one: o b. p c. t O d. any of the above

Q4. Let 1.01 0.99 0.99 0.98 (a) Find the eigenvalue decomposition of A. Recall that λ is an eigenvalue of A if for some u1],u2 (entries of the corresponding eigenvector) we have (1.01 u0.99u20 99u [1] + (0.98-A)u[2] = 0. Another way of saying this is that we want the values of λ such that A-λ| (where I is the 2 x 2 identity matrix) has a non-trivial null space there is a nonzero vector u such that (A-AI)u =...
