How does activity levels affect flexibility? Low levels of activity allow the body to reduce tendon and muscle length. High levels of activity increase muscle mass, and therefore pull on the tendon and bone, reducing flexibility. Low levels of activity allows the tendons to relax and lengthen, allowing greater flexibility. High levels of activity increases blood flow to the tendons, pulling them tighter. A modified sit and reach involves a tape measure starting at: 10 inches, with the measuring tape extending away from the body until it becomes zero.

4. Morphine is a natural alkaloid derived from the opium poppy and a commonly used analgesic for moderate to severe pain. Heroin is a semi-synthetic opioid, created in the laboratory by acylating morphine. Heroin is more potent than morphine and passes through the blood-brain barrier more readily.

A worker at the local Department of Motor Vehicles (DMV) claims that 60% of teenagers smile in their driver's license photo. In a random sample of 10 teenagers from last month's new driver's licenses, only 4 of them were smiling in their photos. To see how unusual this sample is, 100 simulated trials were conducted under the assumption that 60% of teenagers smile for their driver's license photo. There is about an 8% chance that 4 or fewer teenagers smiled for their photo. This is not unusual and is not convincing evidence that the true probability is less than 60%.

What are you drinking? Environmental Protection Agency standards require that the amount of lead in drinking water be less than 15 micrograms per liter. Ten samples of water from a particular source have the following concentrations, in units of micrograms per liter: 11.9, 14.4, 11.6, 14.5, 15.6, 8.7, 12.5, 8.6, 11.5, 17.5 (a) Explain why it is necessary to check that the population is approximately normal before performing a hypothesis test. It is necessary to check that the population is approximately normal because the sample size is small (n ≤ 30). (b) Following is a dotplot of the data. Is it reasonable to assume that the population is approximately normal? (c) Assume that the population standard deviation is σ=4. Perform a hypothesis test at the α=0.10 level using the critical value method with the table to determine whether you can conclude that the mean concentration of lead meets the EPA standard. What do you conclude? State the null and alternate hypotheses.
