Question

Consider the observed frequency distribution for the following set of grouped random variables:
Random Variable, x Frequency, fo
Less than 80 ........ 10
80 to under 100 ....... 14
100 to under 120 ...... 19
120 and more ........ 7
Total ............ 50
Perform a chisquare test using α = 0.05 to determine if the observed frequencies follow the normal probability distribution with μ = 100 and σ = 20.
