Hypothesis testing with one sample

Testing a Claim About a Standard Deviation or Variance

Systolic Blood Pressure for Women: Systolic blood pressure results from contraction of the heart. Based on past results from the National Health Survey, it is claimed that women have systolic blood pressures with a mean and standard deviation of 130.7 and 23.4, respectively. Use the systolic blood pressures of women listed in the below Data Set to test the claim that the sample comes from a population with a standard deviation of 23.4.
