Question Chapte Exercise/ Page
r example
Week 1 (1-8)
‘’Calculate the (estimated) marginal probabilities 6.2 6.16, 6.17 181
for …..’’
Marginal probabilities is computed by adding across rows or down columns and divided
by all values.
‘’Calculate the joint probabilities and the expected 6.3 6,27, 6.28, 6.52, 181
frequencies for all possible combinations’’. 6.56
Assuming that the null hypothesis is true then events A and B are independent. Then
calculate: P(A & B) = P(A) x P(B). To calculate frequencies the probability should be
multiplied with all values.
“Find the probability that a student has received 7.1 7.20, 7.34 223
delivery of two or more pizzas this month”.
“Calculate the mean and the standard deviation”. 7.1 7.35 224
“What is the probability that…” or: “find the 7.4 7.87, 7.92, 7.96, 245
probability of the following events”. 7.105 246
“Draw the density function” 8.1 8.4 263
“Find P(X>25), uniformly distributed” 8.1 8.4, 8.6 263
“What is the probability that... (normally 8.2 All exercises on
distributed) p. 278/279
“How many … should he have in stock?” 8.2 ROP > 8.63 280
Week 2 (9,10,11)
“Find the probability that a random sample of…” 9.1 9.1 t/m 9.28 313
“Find the probability that ‘p-hat’ is….” 9.2 9.30 t/m 9.41 320
“Find the probability that the mean (X̄) of sample 1 9.3 9.45, 9.46, 9.47 323
is greater than the mean of sample 2”

confidence” (with ∂ known) 339
“Estimate the population mean with 90% 12.1 12.3, 12.4, 12.5 402
confidence” (with s known)
