I need help with just the parts I got wrong, thanks! at9 8 E.046 that roughly...
It is known that roughly 2/3 of all human beings have a dominant right foot or eye. Is there also right-sided dominance in kissing behavior? An article reported that in a random sample of 124 kissing couples, both people in 77 of the couples tended to lean more to the right than to the left. (Use α = 0.05.) (a) If 2/3 of all kissing couples exhibit this right-leaning behavior, what is the probability that the number in a sample...
It is known that roughly 2/3 of all human beings have a dominant right foot or eye. Is there also right-sided dominance in kissing behavior? An article reported that in a random sample of 136 kissing couples, both people in 88 of the couples tended to lean more to the right than to the left. (Use ? = 0.05.) (a) If 2/3 of all kissing couples exhibit this right-leaning behavior, what is the probability that the number in a sample...

SET THREE: Chapter 6, Section 1-HT, Exercise 046 Use the normal distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from a random sample and use a 5% significance level. Test H0 : p=0.5 vs Ha : p>0.5 using the sample results p^=0.60 with n=25 Round your answer for the test statistic to two decimal places, and your answer for the p-value to three decimal places. test statistic = ________________ p-value...
I need help with questions A-1 and B-1. Thanks Consider the following hypotheses: HO: u = 120 HA: U 120 The population is normally distributed with a population standard deviation of 46. (You may find it useful to reference the appropriate table: z table or t table) a-1. Calculate the value of the test statistic with x = 132 and n = 50. (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) %...
Part of the same question, need all of those parts answered. Double-check them as I have been getting the wrong answer. Thank you! A manufacturer of nickel-hydrogen batteries randomly selects 100 nickel plates for test cells, cycles them a specified number of times, and determines that 14 of the plates have blistered. (a) Does this provide compelling evidence for concluding that more than 10% of all plates blister under such circumstances? State and test the appropriate hypotheses using a significance...
Just need C), D), E). (I got a t value od 1.8856) Sportscasters are interested in whether professional golfers play better in their first round. Consider the following data. Let B=score in the final round of a professional golf tournament and A=score in the first round of a professional golf tournament. A random sample of 5 finalists in the British Open had the following data: Player B (last round) A (first round) 1 73 66 2 68 70 3 73...
#not sure if i got the first parts right but really not sure about last parts. thank you for any help!!! A genetic experiment involving peas yielded one sample of offspring consisting of 449 green peas and 162 yellow peas. Use a 0.01 significance level to test the claim that under the same circumstances, 26% of offspring peas will be yellow. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses...
I got a. but I need help with b, c, and d please. b. what is the test statistic? c. Find the P value d. what is the null hypothesis and what do you conclude about it? 8.2.5 Question Help A certain drug is used to treat asthma. In a clinical trial of the drug, 20 of 273 treated subjects expenenced headaches (based on data from the manufacturer) The accompanying calculator display shows results from a test of the claim...
please i need help with problem please show all the steps and round values according to it thank you As the population ages, there is increasing concern about accident-related injuries to the elderly. An artide reported on an experiment in which the medium lean engle-the farthe subject is able to lean and still recover in one step-was determined for both a sample of younger females (21-29 years) and a sample of older Pomale (67-8 years. The following observations are consistent...
