In a randomized, double-blind experiment, 120 babies were randomly divided into a treatment group (n₁ =60) and a control group (n₂ = 60). After the study, the treatment group had a mean serum retinol concentration of 47.34 micrograms per deciliter (µg/dL) with a standard deviation of 16.05 µg/dL, while the control group had a mean serum retinol concentration of 10.49 µg/dL with a standard deviation of 8.23 µg/dL. Does the treatment group have a higher standard deviation for serum retinol concentration than the control group at the a= 0.05 level of significance? It is known that serum retinol concentration is normally distributed. Use the P-value approach to perform the test. Let o, represent the population standard deviation for the treatment group and 6₂ represent the population standard deviation for the control group.
