the average length of string a and string d is 10x cm . the average length of string b and string c is 8x cm . the average lengt

klasskru [66]

Answer:

a= 18x

Step-by-step explanation:

(a+d)/2 = 10x (1)

(b +c)/2 = 8x (2)

(b+c+d)/3 = 6x (3)

From the equation 2, we have (b+c)= 8x *2 = 16x

From the equation 3, we have d= 6x*3 - (b+c)= 18x- 16x = 2x

From the equation 1, we have a= 10x*2 -d= 20x - 2x= 18x

7 . Sampling distribution of the difference between two means A statistician is interested in the effectiveness of a weight-loss

UkoKoshka [18]

Answer:

0.229

Step-by-step explanation:

Given that the difference between the two sample means follows anormal distribution with a mean of11.00 and standard deviation equal to1.4387

A statistician is interested in the effectiveness of a weight-loss supplement. She randomly selects two independent samples. Individuals in the first sample of size n1 = 24 take the weight-loss supplement. Individuals in the second sample of size n2 = 21 take a placebo. Individuals in both samples follow identical exercise and diet programs. At the end of the study, the statistician measures the weight loss (in percent) of each participant.

We find that mean difference actual = 13-2 = 11

Probability that difference >12 =P(Z> $\frac{12-11}{1.3487} \\$ )

=P(Z>0.742)=.0.229
