Long-term exposure to beryllium can cause people to become sensitized. Once an individual is sensitized, continuedexposure can result in chronic beryllium disease, which involves scarring of the lungs. In a study of the effects of exposure toberyllium, workers were categorized by their duration of exposure (in years) and by their disease status (diseased, sensitized, ornormal). The results were as follows:Duration of Exposure<111 to <5> 5Diseased15719Sensitized122214Normal66145197Send data to ExcelTest the hypothesis of independence.

10% of all Americans suffer from sleep apnea. A researcher suspects that a higher percentage of those who live in the inner city have sleep apnea. Of the 389 people from the inner city surveyed, 47 of them suffered from sleep apnea. What can be concluded at the level of significance of α= 0.01? b.The null and alternative hypotheses would be: Ho: (please enter a decimal) H1: (Please enter a decimal) c. The test statistic = (please show your answer to 3 decimal places.) d.The p-value = (Please show your answer to 4 decimal places.)
Kenya is a behavioral psychologist who works with children on the Autism Spectrum. She suggests that blowing bubbles may effect children's eye contact (she hasn't predicted if it would increase or decrease). She works with a student who makes 5 points of eye contact in a session. How would the NULL hypothesis be state for her study using bubbles? µ < 5 µ = 5 µ > 5 µ ≠ 5
A highway department is studying the relationship between traffic flow and speed. The following model has been hypothesized: y = B₁ + B₁x + ε where y = traffic flow in vehicles per hour x = vehicle speed in miles per hour. The following data were collected during rush hour for six highways leading out of the city.

Refer image to questions -What is the appropriate test to answer this question? -The null and alternative hypotheses are (choose from below) H0: π = 0.7, H1: π ≠ 0.7 H0: β = 0, H1: β ≠ 0 H0: μ = 0, H1: μ ≠ 0 H0: μ = 70, H1: μ ≠ 70 H0: μ1- μ2 = 0, H1: μ1- μ2 ≠ 0 - How can you justify the assumption for this test? (choose from below) -Since nπ and n(1-π) are both ≥5, the Central Limit Theorem applies and we can assume that p arises from a normal distribution -The shape of the histogram indicates that the scores may be from a normal distribution and/or the sample size is reasonably large so the sample mean will be from a normal population -The boxplots indicate that the samples are fairly symmetric and the spreads are similar, so we can assume both sets of data come from normal distributions with the same spread -The points are randomly scattered around a straight line, so the assumptions of linearity and constant spread are satisfied. The shape of the histogram indicates that the…
10. The null and alternative hypotheses For each pair of hypotheses that follows, decide whether H₀ and H₁ are set up correctly as the null and alternative hypotheses for a hypothesis test. If so, select “Valid” from the drop down menu. If not, select “Invalid”. 1 H₀: M = 145 2 H₀: μ = 19 H₁: M ≠ 145 H₁: μ ≠ 19 3 H₀: μ = 324 4 H₀: µ = 59 H₁: μ ≠ 324 H₁: µ ≠ 66 You evaluate the by assuming that it is true and testing the reasonableness of this assumption by calculating the probability of getting the results if chance alone is operating.

A car manufacturer claims that its latest model can average 60 miles per gallon on the highway - and an auto magazine's editor wants to put that claim to the test. (a) Write the null hypothesis for this situation. (b) Write the alternate hypothesis, if the editor wants to prove that the actual miles per gallon is lower than what's being claimed. (c) Write the alternate hypothesis, if the editor wants to prove that the actual miles per gallon is simply different from what's being claimed.
An engineer working for a large agribusiness has developed two types of soil additives he calls Add1 and Add2. The engineer wants to test whether there is any difference between the two additives in the mean yield of tomato plants grown using these additives. The engineer studies a random sample of 12 tomato plants grown using Add1 and random sample of 13 tomato plants grown using Add2. (These samples are chosen independently.) When the plants are harvested, he counts their yields. These data are shown in the table. Yields (in number of tomatoes) Add1 162, 168, 175, 167, 181, 180, 187, 171, 167, 191, 166, 172 Add2 178, 185, 185, 227, 145, 202, 218, 211, 156, 164, 173, 194, 166 Send data to calculator Send data to Excel Assume that the two populations of yields are approximately normally distributed. Can the engineer conclude, at the 0.10 level of significance, that there is a difference between the population mean of the yields of tomato plants grown with Addi and the population mean…
