A) Estimate the mean systolic blood pressure of all miners.B) Estimate the standard deviation of the systolic blood pressure.C) Use the estimates in parts A and B along with the fact that the blood pressures are normally distributed to obtain an estimate of the proportion of all miners whose blood pressure exceeds 150.

1 11. Use the data of ITOD. the size of a single-family household in 12. Suppose that the systolic blood pressure of a Worker in the mining : dusty is normally distributed. Suppose also that a faildoin sample of such workers yielded the following blood pressures: 129, 134, 142, 114, 120, 116, 133, 142, 138, 148, 129, 133, 141
