For a standard normal distribution
1. p(z is less than or equal to 1.33)
2. p(z is less than or equal to -2.33)
3. p(z is greater than or equal to 2.35)
4. p(-2.33 is less than z is less than 2.33)
5. p(2.33 is less than z is less than 2.95)

give probabilities for 0<Z<infinity. For these ranges, you can read directly, for example, P(Z<1.96)=0.975. So for #1, you read directly on the line 1.3 and column 0.03. For #2, we note that the distribution is symmetrical about Z=0, so P(Z<-2.33) is the same as P(Z>2.33) which again is the same as 1-P(Z<2.33) because we know that the area under a probability distribution function adds up to 1. For the remaining questions, work is similar to #2.
