The chilbirth weights (in kilograms) are recorded for a sample of 36 male born to mothers taking a B vitamin supplement. The results are as follows:

  • Mean = 3.75 kg
  • Std Dev. = 0.976 kg
  • N = 36 (sample size)

the past studies that the average weight of all male babies is 3.39 kg. Does it appear that vitamins given to mothers makes a difference in a baby's birth weight, using a 0.05-level of significance. What is the exact margin of error?

The test is inclusive at the 0.05 level of significance. In other words, we do not feel confident enough, based on our sample, to reject the null hypothesis and accepted the alternative.

It seems that the weight of babies whose mothers get the special vitamin supplement are significantly different from other babies, and the margin of error of this statement is approximately 0.027 or 2.7%.

It seems that the weight of babies whose mothers get the special vitamin supplement are not significantly different from other babies. The margin of error is 10% or more.
