Please I need help with these questions. Please note each picture has a number in the left corner of it, example 8.2.4 please use those numbers to identify the solutions and explanations example 8.2.4 ...... The reason I say that, is because is going to help me to identify them faster. Thanks for comprehension and support, Thanks! Also note that most of them has been already answered, don't need explanations or solutions for those has been already answered, only for those are needed of it. Also, note you mind find the data need it in split it pics, Thanks! ?
8.2.17-T Assigned Media Question Help A random sample of 868 births included 433 boys. Use a 0.10 significance level to test the claim that 51.1% of newborn babies are boys. Do the results support the belief that 51.1% of newborn babies are boys? H1: p 0.511 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is - 0.72.

Use What are the null and alternative hypotheses? either the P-value method or the traditional method of testing hypotheses. Company A uses a new production method to manufacture aircraft altimeters. A simple random sample of new O A. Ho: 6# 32.2 ft OB. Ho: 6 = 32.2 ft altimeters resulted in errors listed below. Use a 0.05 level of significance to test the claim that the new production method has errors with a standard deviation greater than 32.2 it, which was the standard deviation for the old H,: 6 = 32 2 ft H,: 0# 32.2 ft production method. If it appears that the standard deviation is greater, does the new production method appear to O C. H: 6 > 32.2 ft OD. H: 6 32.2 ft Find the test statistic. x2 = 0 (Round to two decimal places as needed.)8.4. 14-T Assigned Media Question Help The data table contains waiting times of customers at a bank, where customers enter a single waiting line that feeds three teller windows. Test the claim that the standard deviation of waiting times is less than 2.3 minutes, which is the standard deviation of waiting times at the same bank when separate waiting lines are used at each teller window. Use a significance level of 0.025. Complete parts (a) through (d) below. Click on the icon to view the data. a. Identify the null and alternative hypotheses. Choose the correct answer below. O A.
