Answer:
95% confidence interval for the variance of the bowling ball weight is between a lower limit of 13.328 pounds and an upper limit of 14.672 pounds.
Step-by-step explanation:
Confidence interval is given as weight +/- margin of error (E)
weight = 14 pounds
sample sd = 0.94 pound
n = 10
degree of freedom = n - 1 = 10 - 1 = 9
confidence level (C) = 95% = 0.95
significance level = 1 - C = 1 - 0.95 = 0.05 = 5%
critical value (t) corresponding to 9 degrees of freedom and 5% significance level is 2.262
E = t × sample sd/√n = 2.262×0.94/√10 = 0.672 pounds
Lower limit of weight = weight - E = 14 - 0.672 = 13.328 pounds
Upper limit of weight = weight + E = 14 + 0.672 = 14.672 pounds.
95% confidence interval is (13.328, 14.672)
5% of $200=$10
she has $210 after the first year
5% of $210=$10.5
she has $220.5 after the second year.
Answer:
I believe it would be A) 2 + m - 1 + - m
55 cause 45 + 15 = 60+40 =100]
Answer:
Step-by-step explanation:
The reflection of a function 
along the 
is given by 
.
Here the given function is 
. Therefore the reflection would be .
To find reflection draw the graph of it and think about how the graph of its mirror image would be. You would arrive at the reflection function.
