I'll type the last to answer choices below6.36The correct value of Z, t, or r is not listed in alternatives a through e, even when talking into consideration a rounding error of plus or minus 0.16.May you please help me out here I'm not understanding.

A researcher knows that "maternal attachment" (MA) scores of 18 month old toddlers who were breastfed is normally distributed with u = 7.5 and o' = 1.2. High scores indicate greater maternal attachment with the MA test; the maximum score is 10. She speculates that 18 month old toddlers who are not breastfed will differ in terms of their MA scores from those who were breastfed. With a sample of N = 20 non- breastfed toddlers, the researcher obtained the MA scores below. MA scores of non- breastfed toddlers: 3, 5, 4, 3, 7, 2, 3, 7, 9, 4, 6, 8, 2, 8, 8, 9, 6, 7, 7, 5 Complete step 3 of the hypothesis testing procedure and calculate the appropriate z , t, or r. Round to the nearest hundredths place. If your calculated z , t, or r is not identical to one of the values below, but within plus or minus 0.16 of an answer below, assume it's a rounding error and select the answer that is closest to your calculated value. Ignore the minus sign if your calculated z or t is negative, but if you calculate r and it's negative, of course, write the minus sign. O -62 O 2.96 3.15 5.97
