Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correctsymbol (µ, p, Η) for the indicated parameter. An entomologist writes an article in a scientific journalwhich claims that fewer than 16 in ten thousand male fireflies are unable to produce light due to agenetic mutation. Use the parameter p, the true proportion of fireflies unable to produce light.
A tire company claims that their new tires will have an average life of 149000 miles. A consumer group wishes to test this claim at the a= 0.10 level of significance. Which would be correct hypotheses for this test? Ho: u = 149000, H1: 4 # 149000 Ho : µ + 149000, H1 : µ O Ho: u = 149000, H1 : u 149000 A random sample of 52 sets of tires were tested and had an average life of 148928 miles, with a standard deviation of 77.6 miles. Find the test statistic (2 decimal places): Give the P-value (4 decimal places, if less than 0.001 answer 0): Which is the correct result: O Reject the Null Hypothesis O Do not Reject the Null Hypothesis Which would be the appropriate conclusion? O There is not significant evidence to suggest that the average life of the tires is different than 149000 O There is significant evidence to suggest that the average life of the tires is different than 149000 miles

The Cadet is a popular model of sport utility vehicle, known for its relatively high resale value. For a random sample of 33 Cadets, each bought "new" two years ago and each sold "used" within the past month, the least-squares regression equation relating the two variables mileage (denoted by x) and used selling price (denoted by y, in dollars) was y = 39.52 – 0.56x . The standard error of the slope of this least-squares regression line was approximately 0.43. Based on this information, test for a significant linear relationship between the two variables by doing a hypothesis test regarding the population slope B,. (Assume that the variable y follows a normal distribution for each value of x and that the other regression assumptions are satisfied.) Use the 0.10 level of significance, and perform a two-tailed test. Then fill in the table below. (If necessary, consult a list of formulas.)

K A poll was conducted to investigate opinions about global warming. The respondents who answered yes when asked if there is solid evidence that the earth is getting warmer were then asked to select a cause of global warming. The results are given in the accompanying data table. Use a 0.01 significance level to test the claim that the sex of the respondent is independent of the choice for the cause of global warming.

Answers: 1. a) χ2 = 4.112, do not reject H0: gender and age of contracting the disease are independent; b) χ2 = 14.03, reject H0: the data do not support the researcher's beliefs; Answer back quickly plz c) χ2 = 2.068, do not reject H0: it appears that this belief is not supported (there is no evidence to suggest that the belief is correct).
