Answer:
(1.1155 ; 1.1245)
Step-by-step explanation:
Given that :
Sample mean, xbar = 1.12
Sample standard deviation, s = 0.011
Sample size, n = 25
Since we are using the sample standard deviation, we use the T distribution ;
The confidence interval is defined as :
C. I = Xbar ± Tcritical * s/√(n)
Degree of freedom, df = n - 1 = 24
Tcritical(0.05, 24) = 2.064
C. I = 1.12 ± (2.064 * 0.011 / √25)
C.I = 1.12 ± 0.0045408
Lower boundary = (1.12 - 0.0045408) = 1.1155
Upper boundary = (1.12 + 0.0045408) = 1.1245
(1.1155 ; 1.1245)
Austin would have 6 jelly beans and Alex would have 18 because if Alex were to have three times as many jellybeans as Austin that means Austin will have one times and Alex would have three times which equals four so you would have to divide 4÷24 which gives them six for each group
Answer: 11
= 10.67707825
rounded to nearest whole number would be 11
The answer is C because when it reflects the 4 stays negative and the 6 because negative because it reflected on the negative side
Hope this helped! :))
