-The mean systolic blood pressure for a random sample of 28 women aged 18-24 is 114.8 mm Hg and the standard deviation is 12.6 mm Hg. Construct a 90% confidence interval for the standard
Deviation Ϭ, of the systolic blood pressures of all women aged 18-24.

• A) \(9.8\) to \(17.6 \mathrm {~mm} \mathrm { Hg }\)
• B) \(10.2\) to \(15.9 \mathrm {~mm} \mathrm { Hg }\)
• C) \(10.8\) to \(15.4 \mathrm {~mm} \mathrm { Hg }\)
