QUESTION 1A researcher hypothesizes that children will choose to eat cereals in colorful boxes over those in plain boxes. To test this hypothesis, the researcher records the number of bites that 24 children take of a food given to them from colorful boxes versus plain boxes. If the mean difference (colorful boxes – plain packaging) is MD = 13 and SMD = 1.64, then(a) calculate the 95% confidence interval for these related samples and(b) can we conclude that cereals packaged in colorful boxes significantly changes the number of bites that children took compared to plain packaging? Summarize your conclusion in a sentence.
