Need a little help. Please help You wish to test the claim that the average IQ score is less than 100 at the .10 significance level. You determine the hypotheses are: Ho : μ = 100 H 1 : μ < 100 You take a simple random sample of 41 individuals and find the mean IQ score is 97.2, with a standard deviation of 14.9. Let's consider testing this hypothesis two ways: once with assuming the population standard deviation is...
Please Help! Need to confirm my answer. You wish to test the claim that the average IQ score is less than 100 at the .01 significance level. You determine the hypotheses are: Ho: μ = 100 H1: μ < 100 You take a simple random sample of 100 individuals and find the mean IQ score is 95.7, with a standard deviation of 16. Let's consider testing this hypothesis two ways: once with assuming the population standard deviation is not known...
In 2001, 5.6% of people used cocaine. This year, a company wishes to use their employment drug screening to test a claim. They take a simple random sample of 2877 job applicants and find that 131 individuals fail the drug test for cocaine. They want to test the claim that the proportion of the population failing the test is lower than 5.6%. Use .05 for the significance level. Round to three decimal places where appropriate. Hypotheses: H o : p...
You wish to test the following claim ( H a ) at a significance level of α = 0.02 . H o : μ = 51.6 H a : μ < 51.6 You believe the population is normally distributed and you know the population standard deviation is σ = 8.7 . You obtain a sample mean of M = 49.3 for a sample of size n = 51 . What is the test statistic for this sample? (Report answer accurate...
You wish to test the following claim ( H a ) at a significance level of α = 0.002 . H o : p = 0.46 H a : p < 0.46 You obtain a sample of size n = 295 in which there are 113 successful observations. What is the test statistic for this sample? (Report answer accurate to two decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.)...
PLEASE HELP AND SHOW WORK.... AMD IF THERE IS A CALCULATOR WAY PLEASE SHOW IT ON TI84. You wish to test the following claim (Ha) at a significance level of α-0.02 Ho: μ = 52.4 52.4 Ha: μ You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n 20 with mean M 55.8 and a standard deviation of SD 6.3. What is the p-value for this sample? (Report...
You wish to test the following claim a significance level of α = 0.05 . H o : p = 0.5 H a : p > 0.5 You obtain a sample of size n = 461 in which there are 257 successful observations. What is the test statistic for this sample? test statistic = Round to 3 decimal places. What is the p-value for this sample? P-value = Use Technology Round to 4 decimal places. The p-value is... less than...
You wish to test the following claim (H1) at a significance level of α=0.10. Ho:p1=p2 H1:p1<p2 You obtain a sample from the first population with 423 successes and 41 failures. You obtain a sample from the second population with 294 successes and 25 failures. What is the critical value for this test?

Please use TI-83+ calculator to solve this. thank you! You wish to test the following claim (HaHa) at a significance level of α=0.10α=0.10. Ho:p1=p2Ho:p1=p2 Ha:p1<p2Ha:p1<p2 You obtain 26.7% successes in a sample of size n1=333n1=333 from the first population. You obtain 28.2% successes in a sample of size n2=476n2=476 from the second population. For this test, you should NOT use the continuity correction, and you should use the normal distribution as an approximation for the binomial distribution. What is the...
