The mean weight of a newborn baby in North America is 120 ounces (oz). We want to test the hypothesis that mothers with low socioeconomic status have babies whose weight at birth is lower than 120 oz. Let a be the mean weight of a newborn baby whose mother has a low socioeconomic status. Set.up a test of hypotheses and explain when type l error or type Il error occur by choosing the correct statement from the list below. Ho: - 120 versus Hy : p < 120. A Type lerror occurs when we conclude that the mean of a newborn baby whose mother has a low socioeconomic status is 120 oz, but in fact this weight is lower than 120 oz. Ho: - 120 versus H1 : µ < 120. A Type i error occurs when we conclude that the mean weight of a newborn baby whose mother has a low socioeconomic status is lower than 120 oz, when in fact it is not true. Ho: #2 120 versus Hq : p< 120. A Type I error occurs when we conclude that the mean weight of a newborn baby whose mother has Oa low socioeconomic status is lower than 120 oz, when in fact it is not true. Ho: 2 120 versus Hy : µ < 120. A Type Il error occurs when we conclude that the mean of a newborn baby whose mother has a low socioeconomic status is 120 oz, but in fact this weight is lower than 120 oz. Ho: - 120 versus Hị :p< 120. A Type l error occurs when we conclude that the mean weight of a newborm baby whose mother has a low socioeconomic status is lower than 120 oz, when in fact it is not true.

Transcribed Image Text:The mean weight of a newborn baby in North America is 120 ounces (oz). We want to test the hypothesis that mothers with low socioeconomic
status have babies whose weight at birth is lower than 120 oz. Let u be the mean weight of a newborn baby whose mother has a low
socioeconomic status. Set-up a test of hypotheses and explain when type I error or type Il error occur by choosing the correct statement from the
list below.
Ho: H- 120 versus H1:p< 120. A Type i error occurs when we conclude that the mean of a newborm baby whose mother has a low
socioeconomic status is 120 oz, but in fact this weight is lower than 120 oz.
Ho : H- 120 versus H1 : u < 120. A Type i error occurs when we conclude that the mean weight of a newborn baby whose mother has
a low socioeconomic status is lower than 120 oz, when in fact it is not true.
Ho: H2 120 versus H1 : < 120. A Type 1error occurs when we conclude that the mean weight of a newborm baby whose mother has
a low socioeconomic status is lower than 120 oz, when in fact it is not true.
Ho: 2 120 versus H1 : H< 120. A Type ll error occurs when we conclude that the mean of a newborn baby whose mother has a low
socioeconomic status is 120 oz, but in fact this weight is lower than 120 oz.
Ho: u= 120 versus H1 : < 120. A Type ll error occurs when we conclude that the mean weight of a newbom baby whose mother has
a low socioeconomic status is lower than 120 oz, when in fact it is not true.
