Question Help The recommended dietary allowance (RDA) ofron for adult females is 18 miligrams img per day. The genron intakes ima) were obtained for 45 random adult formales. At the significance level do the data suggest that aduit females are, on average, getting less than the RDA of 18 mg of tron? Assume that the population standard deviation is 48 mg Preliminary data analyses indicate that applying the z-test is reasonable. (Note: 14.75 mg) Cck here to view the iron...
section 9.4 Suppose the mean height of women age 20 years or older in a certain country is 62.5 inches. One hundred randomly selected women in a certain city had a mean height of 61.0 inches. At the 1% significance level, do the data provide sufficient evidence to conclude that the mean height of women in the city differs from the national mean? Assume that the population standard deviation of the heights of women in the city is 4.1 inches...
