Step-by-step explanation:
Answer:
(364.595 ; 391.405)
Step-by-step explanation:
Given the sample data:
406, 385, 389, 383, 352, 379, 388, 343, 368, 387
Using calculator :
Sample mean, xbar = 378
Standard deviation, s = 18.74
Confidence interval :
Xbar ± Margin of error
Margin of Error = Tcritical * s/√n
TCritical at df = 24 ; 0.05 = 2.262
Margin of Error = 2.262 * 18.74/√10 = 13.405
Lower boundary = (378 - 13.405) = 364.595
Upper boundary = (378 + 13.405) = 391.405
(364.595 ; 391.405)
Answer: 14/7 = 7/1 = 7
Step-by-step explanation: there is the formula for it.
Y2 - Y1
X2 - X1
4(3+2(5))-6
4(3+10)-6
12+40-6
52-6
46
46 is the answer :))
