1. in a survey sample of 83 respondents, about 30.1 percent of the sample work less than 40 hours per week. calculate a 68 percent confidence interval for the proportion of persons who work less than 40 hours per week.

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)
