For questions 1 through 6, please refer to the following information: Studies have shown that

low vitamin D is associated with impaired fertility, endometriosis, and polycystic ovary

syndrome. Vitamin D regulates the antimullerian hormone (AMH), follicle-stimulating hormone,

mRNA, and expression of genes in reproductive tissues, implicating a role in female

reproduction. Lata et al. conducted a prospective study to compare AMH levels in infertile and

fertile females 05 significance level, use the confidence interval method to test the claim that

infertile females have different AMH levels compared to fertile females. To do so, answer each

of the following questions.

with vitamin D deficiency. Among the 35 fertile females (group 1), the mean

AMH level was 3.47 with a standard deviation of 2.59. Among the 35 infertile females (group 2),

the mean AMH level was 1.94 with a standard deviation of 1.30. Assuming the variances are

unequal and a 0.

What is the standard error? (1 point)

a. 0.11

b. 0.33

c. 0.49

d. 0.99
