- I need up solving this problem part A and part BPlease answer the following and show how to solve using the graphing calculator. Thank youGenerally speaking, the fewer times your heart beats every minute, the healthier you are, and a longer life span will be more likely. Ben and Sierra compared their heart rates. Sierra had been exercising every day for at least a year. Her heart rate during the 45 minutes each day that she exercised was 150 beats per minute. But her heart rate dropped to 60 beats per minute for the rest of the day. Ben didn’t exercise at all and had a daylong average heart rate of 72 beats per minute. During the last leap year, whose heart beat more times and how many more times did it beat?
- You manage a team of 4 employees. The entire team is responsible for completing 4 projects on time. The time to complete the task is 4 weeks, and this is the time needed and is based on a 56-hour work week for each team member. Each team member will work 7 days a week, since this is a priority project and, must be completed on time. The names of the 4 team members are A, B, C, and D. Based on historical data, at least 1 of the 4 team members calls in sick at least (and only) 1 time per week. Based on this information, what is the probability that the project will be completed on time? If the probability of the project not being completed on time is > 0, what will you do to ensure that the project will be completed on time? What AI systems would you put in place to ensure that you can complete current and future projects? You are to select a strategy that is most feasible and you must justify your answer and provide an analysis.Luke's teacher has assigned each student in his class an online quiz, which is made up of 10 multiple-choice questions with 4 options each. Luke hasn't been paying attention in class and has to guess on each question. However, his teacher allows each student to take the quiz three times and will record the highest of the three scores. A passing score is 6 or more correct out of 10. We want to perform a simulation to estimate the score that Luke will earn on the quiz if he guesses at random on all the questions. The dotplot shows Luke's simulated quiz score in 50 trials of the simulation. Doug is in the same class and claims to understand some of the material. 1 N 10000 2 …………………………………at 3 …………………… 4 3 ……………………●●●●●▬ 5 Simulated quiz score -●●●●● 10 6 7 If Doug scored 8 points on the quiz, is there convincing evidence that he understands some of the material? Why or why not? Yes, it is unlikely that Doug would score higher than 6 out of 10 based upon randomly guessing the answers. Since…The principal of Paul Revere High School bragged that his 2016 graduating class of 1500 students achieved impressive scores on their ACT exams. He announced that an “astounding” 36% of the class got a score of 29 or higher, 54% got a score of 21 to 28, and only 10% less than 21. You want to test whether these ACT results are really that astounding. You visit the ACT website to see that the national results are 34% getting a score over 28, 58% getting 21 to 28, and 8% less than 21. Test whether or not the principal is correct to brag that his proportions were more impressive than the national performance. Use an alpha of 0.05. So I kinda understand the question. I am mostly confused about how to determine the degree of freedom to get the critical value. Like I know the formula is d-C, and C is the number of categories in the word problem, but is there 3? Or am I just totally wrong?
- Please help meA teacher was listening to some of her students talk about how many SnapChats they send during the day. The teacher decided that she wanted to conduct a study to see if the number of SnapChats a student sends per day affects how much time students talk to their friends face-to-face. So, the teacher let her 2nd period class continue sending Snaps as they always have. Then, the teacher told her 5th period that they were to not watch use SnapChat for a whole day. Then, the teacher had students record how many conversations they had with their friends during the week, gathered the data, and analyzed the results. What type of study is this? Experimental or observational?please answer both the questions within 30 minutes. do not answer just one question else i will give negative ratings. make sure you answer both the questions.
- Show full solution. To inspect the quality of the screens for mobile phones produced by Company X, two separate inspection devices are used to test the screens for defects. Basically, a specific screen is tested once using the two inspection devices. Device 1 can detect the presence of defects 99.3% of the time, whereas Device 2 can detect defects 99.7% of the time. Assume that the 2 devices are operating independently from each other. One day, four defective screens were sent for inspection. Let X represent the number of screens that will be correctly tagged as defective by Device 1, while Y represents the number of screens that will be correctly tagged as defective by Device 2. Determine the following:a.) fXY(x,y)b.) fX (x)c.) E(X)Our family brought lots of hot dogs along on our latest camping trip. However, after setting up the tent, we didn’t take care to make sure that the food was safe – and raccoons ate 1/3 of the hot dogs! Grumbling, we cleaned up the mess, then ate 6 hot dogs for lunch. But we forgot to put the rest away when we went hiking, and lost 1/4 of our dwindling supply to jays! Just as a precaution, Mom went to the store and bought enough hot dogs to increase our supply by 2/3. Our campsite neighbors, however, ran out of food, so we gave them 2/9 of our remaining hot dogs and then ate 11 hot dogs for our dinner. That night, bears got 3/4 of the last part of our supply, and in the morning there were only 6 hot dogs left! How many hot dogs did we start with? (Next time maybe we should just bring granola bars...)Please share the solution for the last 2 parts (c & d) in bold. The first three parts answered by your team. In a study of the Gouldian finch, Griffith et al. (2011) looked at stress caused by having an incompatible mate.There are two genetically distinct types of Gouldian finches, one having a red face and the other having a black face. Previous experiments have shown that female finches have a strong preference for mating with males with the same face color as themselves , and that when different face types of finch mate with one another, their offspring are less likely to survive than when both parents are the same type. Researchers paired females sequentially with males of both types in random order,In other words, each female bred twice once with a compatible male and once with an incompatible male.Each time, females produced a brood of young with the assigned male.For each pairing, the researchers measured the blood corticosterone concentration (in units of ng/ml) as an index…
