QUESTION 23"A fitness coach woud like to determine whether her aerobic fitness intervention leads to a significant increase or decrease in the oneheaviest possible weight that can be lifted once) for deadlifts in her group of athletes (n = 13). She finds that the mean differencesum of squared deviation (SS) 96.6. Calculate the t-statistic the fitness coach would observe given this data.

Researchers examined the mechanical properties of webs spun by the orb spider. A table in their published report gives summary statistics for a number of variables in the form of the mean plus or minus the standard error of the mean. This form is very common in scientific publications. For 17 adult female spiders, web areas (in square centimeters, cm2) are 640±37. What are ? and s for these spider webs? (Enter your answer as a whole number for ? and rounded to one decimal place for s ) I know x bar is 640, but what is "s"? Is it the SEM of standard deviation? how to I calculate it?
Spinning a coin, unlike tossing it, may not give heads and tails equal probabilities. I spun a penny 275 times and got 122 heads. We wish to find how significant is this evidence against equal probabilities. a. What is the sample proportion of heads? Round to 3 decimal places. b. Heads do not make up half of the sample. Is this sample evidence that the probabilities of heads and tails are different? Take p to be the probability of getting heads in a spin of a penny. Which hypotheses do we want to test? O Họ: p = 0.5 Họ: p > 0.5 O Ho: p = 0.5 Ho: p < 0.5 O Ho: p = 0.5 Ho: p 0.5 O Ho: p 0.5 Ho: p = 0.5 c. Compute the z test statistic. Z = Round to 2 decimal places.

Suppose you fail to reject the null hypothesis that the mean diameter of a bolt is at most 10 cm. The true mean is 10.02 cm.
A Biomedical engineer is measuring how much current is needed to stimulate the nerve of a rat to create a muscle function. He is measuring 5 rats and wants to evaluate if less current is needed to stimulate a young animal compared to an old animal. The mean of the current to stimulate young animals is 4.6mA. Meuasrements from trials on Old Rats: 6, 6, 12, 7, 8 (in mA) Can the engineer conclude that old rats need more current?
