5 A study of iron deficiency among infants compared samples of infants following different feedingregimens. One group contained breastfed infants, while the children in another group were fed astandard baby formula without any iron supplements. Here are summary results on bloodhemoglobin levels at 12 months of age:GroupBreastfedFormulan2319ybar13.312.4S1.71.8Do the data provide sufficient evidence that the mean hemoglobin level is higher among breastfedbabies? Test using a = 0.05.IN ANSWERING, BE SURE TO ADDRESS EACH OF THE FIVE STEPS IN A TEST OF HYPOTHESIS.

The provided information is as follows:The sample size for the sample 1 is Breastfed is .The sample mean for the sample 1 is .The sample standard deviation is .The sample size for the sample 2 is formula is .The sample size for the sample 2 is .The sample standard deviation is .The level of significance is The null and alternative hypotheses are as follows:.The null hypothesis states that there is no significant difference between the mean hemoglobin level of breastfed babies and the other group of fed standard baby formula.The alternative hypothesis states that the mean hemoglobin level of breastfed babies is higher than the other group of fed standard baby formula.The pooled standard deviation is calculated as follows:Here, we assume that the population variances are equal.The test statistic is calculated as follows:The test statistic is 1.6630.The degree of freedom is calculated as follows:The p-value is calculated as follows:The p-value is calculated using the Excel formula .Here, .0.0521 > 0.05.There is insufficient evidence to reject the null hypothesis.Therefore we may not conclude that the mean hemoglobin level of breastfed babies is higher than the other group of fed standard baby formula.5) The null and alternative hypotheses are as The pooled standard deviation is 1.7457.The test statistic is 1.6630.The p-value is 0.0521.We may not conclude that the mean hemoglobin level of breastfed babies is higher than the other group of fed standard baby formula.
