1. Use one sample t-test to solve for the following:
a. The weights of 11 one month old breastfed babies are found to be 4.64, 4.41, 4.60, 4.50,
3.50, 4.01, 3.99, 4.55, 4.62, 4.80, and 4.00 kg. Based on the standard weights, one
month old babies should weigh 4 kg. Does this indicate that breastfeeding is best for
babies? Use x= 0.05.
b. The reaction time of a coagulant is recorded as follows: 30.26s, 31.4s, 35.6s, 34.8s,
35.26s. The standard reaction time is 32.67 s. Is this sufficient evidence that the
coagulant is effective?
