4Don't copy paste and Twa types of phone operating system are being tested to determine if there is a difference in theproportions of system failures (crashes). Fifteen out of a random sample of 150 phones with Os, had systemfailures within the first eight hours of operation. Nine out of another random sample of 150 phones withOS, had system failures within the first eight hours of operation. OS, is believed to be more stable (havefewer crashes) than OS1.a) What hypotheses should be used in order to test whether there is a difference in the proportions ofsystem failures between the two operating systems?Ho: difference of proportions=HA: difference of proportions=b) What is the point estimate?c) Using a standard error of 0.0312, compute the test statistic.d) What is the p-value?The p-value -O The p value <.001e) Based on the p-value, we should Select an answer v the null hypothesis. There is Select an answer vavidenca that the pronortinns of system failures are different for the two operating systems.a ERUUWIEUIUWSU, Fiease Contact Jackie Staiey Ustaley@yvcc.edu or 509-574-4ampus before the day of the exam if you are having difficulty downloading Respondus on to your computer.Question 1The greatest number of ATP is generated from which nutrient?O carbohydratesO lipidsO fiberOproteins

Solution: Given information: n1= 150 Sample size of phones in sample 1n2= 150 Sample size of phones…

Two types of phone operating system are being tested to determine if there is a difference in the proportions of system failures (crashes). Fifteen out of a random sample of 150 phones with Os, had system failures within the first eight hours of operation. Nine out of another random sample of 150 phones with DS, had system failures within the first eight hours of operation. OS, is believed to be more stable (have Tewer crashes) than OS1. m) What hypotheses should be used in order to test whether there is a difference in the proportions of ystem failures between the two operating systems? Ho: difference of proportions= H: difference of proportions= What is the point estimate?
