In a study of parents' feelings about a required course in sex education., 360 parents, a random sample, are classified according to whether they have one, two, or three or more children in the school system and also whether they feel that the course is poor, adequate, or good. Based on the results shown in the following table, test at the 0.05 level of significance whether there is a relationship between parents' reaction to the course and the number of children that they have in the school system: Number of children 1 2 3 or more Poor 48 40 12 Adequate 55 53 29 Good 57 46 20

Observed frequencies

Number of children	1	2	≥3	Total
Poor	48	40	12	100
Adequate	55	53	29	137
Good	57	46	20	123
Total	160	139	61	360
