Solution Steps

To convert pounds (lb) to kilograms (kg), we use the conversion factor where 1 pound is approximately 0.453592 kilograms. We will multiply each given weight in pounds by this conversion factor and round the result to the nearest tenth.

Step 1: Understand the Conversion Factor

To convert from pounds (lb) to kilograms (kg), we use the conversion factor \(1 \, \text{lb} = 0.4536 \, \text{kg}\).

Step 2: Apply the Conversion

For each weight in pounds, multiply by the conversion factor to get the weight in kilograms. The calculations are as follows:

  1. For \(103.4 \, \text{lb}\): \[ 103.4 \times 0.4536 = 46.91 \, \text{kg} \] Rounded to the nearest tenth: \(46.9 \, \text{kg}\).

  2. For \(21.4 \, \text{lb}\): \[ 21.4 \times 0.4536 = 9.707 \, \text{kg} \] Rounded to the nearest tenth: \(9.7 \, \text{kg}\).

  3. For \(21.32 \, \text{lb}\): \[ 21.32 \times 0.4536 = 9.667 \, \text{kg} \] Rounded to the nearest tenth: \(9.7 \, \text{kg}\).

  4. For \(102.5 \, \text{lb}\): \[ 102.5 \times 0.4536 = 46.51 \, \text{kg} \] Rounded to the nearest tenth: \(46.5 \, \text{kg}\).

Final Answer

\(46.9 \, \text{kg}, 9.7 \, \text{kg}, 9.7 \, \text{kg}, 46.5 \, \text{kg}\)

Douglas Boats is a supplier of boating equipment for the states of Oregon and Washington. It sells 5,000 White Marine WM-4 diesel engines every year. These engines are shipped to Douglas in a shipping container of 100 cubic feet, and Douglas Boats keeps the warehouse full of these WM-4 engines. The warehouse can hold 5,000 cubic feet of boating supplies. Douglas estimates that the ordering cost is 10 per order, and the carrying cost is estimated to be 10 per engine per year. Douglas Boats is considering the possibility of expanding the warehouse for the WM-4 engines. Assume demand is constant throughout the year.

Test whether people with a specific genetic marker are more likely to have suffered from clinical depression than people without the genetic marker, using the information that 40% of the 40 people in a sample with the genetic marker have had clinical depression while 16% of the 775 people in the sample without the genetic marker have had clinical depression. Use subscripts 1 for yes these people have the genetic marker and 2 for no these people do not have the genetic market. (a) Find the relevant sample proportions in each group and the pooled proportion. Round your answers to three decimal places, if necessary. p̂₁=0.400 p̂₂=0.160 p̂=0.172 (b) State the null and alternative hypotheses. (c) Give the test statistic and the p-value. Round your answer for the test statistic to two decimal places and your answer for the p-value to three decimal places.
