Answer:
The correct option is;
After 64 seconds, ABOUT HALF of the brands of milk chocolate ARE LIKELY to melt, and NONE of the brands of dark chocolate ARE LIKELY to melt
Step-by-step explanation:
Here we have for the milk chocolate
Min = 29 s
Lower quartile Q₁ = 44 s
Median = 64 s
Upper quartile Q₂ = 93 s
Max = 129 s
For the dark chocolate
Min = 210 s
Lower quartile Q₁ = 237 s
Median = 259 s
Upper quartile Q₂ = 295 s
Max = 320 s
As seen from the values of the box plot, after the median time of 64 seconds which represents half of the test results of the milk chocolate about half of the brands of milk chocolate are likely to melt, while the dark brands only start to melt after 210 seconds.
Therefore the correct option is
After 64 seconds, ABOUT HALF of the brands of milk chocolate ARE LIKELY to melt, and NONE of the brands of dark chocolate ARE LIKELY to melt.
$2 x 160 = $320 if Mrs Delgado wants to buy individual plant.
160 divided by 20 = 8 Mrs Delgado can buy 8 flats
8 x $30 = $240
How much she saves = $320 - $240 = $80
Mrs Delgado saves $80 if she buys it from flat than separately
<span>a. verify that the conditions for computing a confidence interval are met in this case.
The formula for computing the CI interval is given by:
x_bar+/-z (s/</span>√n<span>)
since:
x_bar=6.67
s=1.88
n=15
The conditions are met because we have all the values necessary for computing CI.
b] </span><span> compute and interpret a 95% confidence interval for the mean number of hours the students at this school sleep each night.
The value of z corresponding to 95% CI is 1.96
thus the 95% CI will be:
6.67+/-1.96(1.88/</span>√15<span>)
=6.67+/-1.96(0.4854)
=6.67+/-0.9514</span>
Answer:
532381.5
Step-by-step explanation:
456327 divided by 6 to get 1/6 = 76054.5
76054.5 x 7 to get 7/6 = 532381.5
or 456327 (6/6) + 76054.5 (1/6) =532381.5
