- find Quartiles (q1, q2 and q3) from the given example. Please solve correct and quickly.Arm circumferences (cm) and heights (cm) are measured from randomly selected adult females. The 146pairs of measurements yield x=34.69cm, y=163.25cm, r=0.075, P-value=0.368, and y=157+0.1826x. Find the best predicted value of y (height) given an adult female with an arm circumference of 40.0cm. Let the predictor variable x be arm circumference and the response variable y be height. Use a 0.05 significance level. The best predicted value is ____cm.Recent studies have shown that adult men suffer from high blood pressure at a lesser rate than do adult women. To test that claim, a research randomly selected 200 of each gender and tested their blood pressure. The results revealed that 49 of the men and 62 of the women suffered from high blood pressure. Can you conclude that the proportion of men with high blood pressure is less than the proportion of women? Use α = 0.05.
- Arm circumferences (cm) and heights (cm) are measured from randomly selected adult females. The 139 pairs of measurements yield x = 31.99 cm, y = 163.33 cm, r= 0.032, P-value = 0.708, and y = 158 + 0.1703x. Find the best predicted value of y (height) given an adult female with an arm circumference of 35.0 cm. Let the predictor variable x be arm circumference and the response variable y be height. Use a 0.05 significance level. %3D ..... The best predicted value is cm. (Round to two decimal places as needed.)To test the effectiveness of a new drug designed to relieve pain, 200 patients were randomly selected and divided into two equal groups. One group of 100 patients was given a pill containing the drug while the other group of 100 was given a placebo. What can we conclude about the effectiveness of the drug if 62 of those actually taking the drug felt a beneficial effect while 41 of the patients taking the placebo felt a beneficial effect? Use α = 0.01.Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 136 to 187cm and weights of 38 to 150kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x=167.69cm, y=81.54kg, r=0.241, P-value=0.016,and y=−101+1.04x. Find the best predicted value of y (weight) given an adult male who is 160cm tall. Use a 0.10 significance level. The best predicted value of y for an adult male who is 160cm tall is
- At α = 0.01, check whether the shoe number differs between male and female students. In the attachment, you send only PART of the data, what the data looks like.Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 135 to 191 cm and weights of 37 to 150kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x=167.79cm, y=81.51kg, r=0.293, P-value=0.003, and y=−106+1.17x. Find the best-predicted value of y (weight) given an adult male who is 147cm tall. Use a 0.10 significance level.To test the effectiveness of a new drug designed to relieve flu symptoms, 200 patients were randomly selected and divided into two equal groups. One group of 100 patients was given a pill containing the drug while the other group of 100 was given a placebo. What can we conclude about the effectiveness of the drug if 62 of those actually taking the drug felt a beneficial effect while 41 of the patients taking the placebo felt a beneficial effect? Use α = 0.05.
- A sample of 800 truck drivers from Minnesota were interviewed randomly and 316 answered they like tunnels. Determine if the sample evidence shows that less than half of the truck drivers like tunnels. Use α=0.05.Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 13 to 192cm and weights 41 to 150kg. Let the predictor variable x be the first variable given. The 100 paired measurements yieldx=167.40cm, y=81.45kg,r=0.368, P-value=0.000,and y=−103+1.03x.Find the best predicted value of y (weight) given an adult male who is 189cm tall. Use a 0.10 significance level. The best predicted value of y for an adult male who is 189cm tall is ___kg.Arm circumferences (cm) and heights (cm) are measured from randomly selected adult females. The 143 pairs of measurements yield x = 32.40 cm, y = 160.39 cm, r=0.072, P-value = 0.393, and y = 157 + 0.1075x. Find the best predicted value of y (height) given an adult female with an arm circumference of 34.0 cm. Let the predictor variable x be arm circumference and the response variable y be height.
