A researcher wants to know if art majors have better visual memory than students in general. We obtain a mean visual memory test score of 50 in a sample of 25 art majors. We know that students in
general score a mean of 45 with a standard deviation of 14 on the same test. Use alpha of .05 and
the 6 steps of hypothesis testing to test this. For full credit, you must number and provide all six
steps of hypothesis testing. Make sure that you clearly describe your interpretation of the results in
step 6.

This punnett square shows the cross between two pants. one parent has round seeds (rr). and the other parent has wrinkled seeds (rr) which best describes their offspring as shown in this cross?

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
