As a Christmas tree farmer, you want to know what seed type is the fastest growing. You plant 14 seeds and wait three years. After three years of growth, the 14 seeds have an average height of 4.24ft and a standard deviation of 0.404ft. The tallest tree has is 4.79ft tall; (a) what is the probability that is random chance? Assume the data follows a normal distribution. (b) Should you use a t-score (t distribution) or a z-score (normal distribution)?

You take your trusty 120 turn solenoid, with 20 cm diameter and spin it at a rate of 10 times per second in a magnetic field that you have constructed with two gigantic neodymium magnets, creating a uniform magnetic field. You are spinning the solenoid so that its rotation axis is perpendicular to the magnetic field direction. a) What field strength do you need to create a peak emf voltage of 150 V? (Hint: use flux as a function of...
