Rigid bar ABC shown in Figure P1.30 is supported by a pin at bracket A and by tie rod (1). Tie rod (1) has a diameter of 5 mm, and it is supported by double-shear pin connections at B and D. The pin at bracket A is a single-shear connection. All pins are 7 mm in diameter. Assume a = 600 mm, b = 300 mm, h = 450 mm, P = 900 N, and θ = 55°. Determine the following:

Construct the indicated confidence interval for the difference between the two population means.

Construct the indicated confidence interval for the difference between the two population means. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Independent samples from two different populations yield the following data. The sample size is 478 for both samples. Find the \(85 \%\) confidence interval for \(\mu_{1}-\mu_{2}\).

\(\bar{x}_{1}=958, \bar{x}_{2}=157, s_{1}=77, s_{2}=88\)

A. \(800<\mu_{1}-\mu_{2}<802\)

A nurse measured the blood pressure of each person who visited her clinic.

A nurse measured the blood pressure of each person who visited her clinic. Following is a relative-frequency histogram for the systolic blood pressure readings for those people aged between 25 and 40. The blood pressure readings were given to the nearest whole number. Approximately what percentage of the people aged 25-40 had a systolic blood pressure reading between 110 and 119 inclusive?

The jet transport B is flying north with a velocity

The jet transport \(B\) is flying north with a velocity \(v_{\mathrm{B}}=600 \mathrm{~km} / \mathrm{h}\) when a smaller aircraft \(A\) passes underneath the transport headed in the \(60^{\circ}\) direction shown. To passengers in \(B\), however, \(A\) appears to be flying sideways and moving east. Determine the actual velocity of \(A\) and the velocity which \(A\) appears to have relative to \(B\).
