A researcher calculated the confidence intervals for the mean blood pressure of men and women from a very large sample, and found the following:

• 95% CI for mean systolic blood pressure in men was 118.1 - 125.2
• 95% CI for mean systolic blood pressure in women was 108.5 - 112.2

Which of the following statements are correct.

Select one or more:

a.

There is a 5% chance that the mean systolic blood pressure for men is outside the range of 118.1 - 125.2.

b.

The standard deviation of systolic blood pressure in men is higher than women.

c.

95% of men will have a systolic blood pressure of 118.1 - 125.2 and 95% of women will have a systolic blood pressure of 108.5 - 112.2

d.

The 95% confidence intervals are a description of the samples, and inference cannot be made on the population means of each group.

e.

We are at least 95% confident that the mean blood pressure is different between genders.
