Let us suppose we have some article reported on a study of potential sources of injury to equine veterinarians conducted at a
university veterinary hospital. Forces on the hand were measured for several common activities that veterinarians engage in when
examining or treating horses. We will consider the forces on the hands for two tasks, lifting and using ultrasound. Assume that both
sample sizes are 6, the sample mean force for lifting was 6.2 pounds with standard deviation 1.5 pounds, and the sample mean force
for using ultrasound was 6.4 pounds with standard deviation 0.3 pounds. Assume that the standard deviations are known.
Suppose that you wanted to detect a true difference in mean force of 0.25 pounds on the hands for these two activities. Under the null
hypothesis, 40 = 0. What level of type II error would you recommend here?
Round your answer to four decimal places (e.g. 98.7654). Use a

We want to assign seats to 10 people, 6 of them only speak Slovene, 1 of them only speaks English, and the remaining 3 speak both Slovene and English, by giving out numbered place cards. In how many ways can we do that so that everyone sits next to at least one person who speaks a common language?arrow_forward

- Aphids are discovered in a pear orchard. The Department of Agriculture has determined that the population of aphids t hours after the orchard has been sprayed is approximated by N(t)=1800−3tln(0.17t)+t where 0<t≤1000. Step 1 of 2: Find N(63). Round to the nearest whole number.arrow_forward1. A telegraph can transmit two different signals: a dot and a dash. We want to encode the 26 letters of the English alphabet and the ten digits 0, 1, 2, . . . , 9 using sequences of these two symbols. What is the smallest integer n such that we can encode all these letters and digits with sequences of length at most n and length at least 1?arrow_forwardUse the graph of y = f(x) to answer the following. 3- 2 -4 -2 -1 1 2 3 4 -1 2 m -3- + (d) Find all x for which f(x) = -2.

- File Preview A gardener has ten different potted plants, and they are spraying the plants with doses of Tertizers. Plants can receive zero or more doses in a session. In the following, we count each possible number of doses the ten plants can receive (the order of spraying in a session does not matter). (a) How many ways are there if there were twelve total doses of a single type of fertilizer? (b) How many ways are there if there are six total doses of a single type of fertilizer, each plant receives no more than one dose? (c) How many ways are there if is was one dose of each of six types of fertilizers? (d) How many ways are there if there are four doses of fertilizer #1 and eight doses of fertilizer #2? (e) How many ways are there if there are four doses of fertilizer #1 and eight doses of fertilizer #2, and each plant receives no more than one dose of fertilizer #1? (f) How many ways are there to do two sessions of spraying, where each plant receives at most two doses total?arrow_forward3. [-/3 Points] DETAILS MY NOTES SCALCET8 7.4.032.
