From the Venn diagram: 15 players like Chemstrand, 17 players like Chemgrass, 13 players like both Chemstrand and Chemgrass while 10 players like neither Chemstrand nor Chemgrass.
The missing values in the frequency table are x - representing the number of players that like both Chemstrand and Chemgrass, y - representing the number of players that like Chemgrass but do not like Chemstrand and z - representing the number of players likes Chemstrand but do not like Chemgrass.
The number of players that like both Chemstrand and Chemgrass is 13. The number of players that like Chemgrass but do not like Chemstrand is 17. The number of players likes Chemstrand but do not like Chemgrass is 15.
Therefore, x = 13, y = 17 and z = 15
"lbs" (pounds) is a measure of force, whereas "kgs" (kilograms) is
a measure of mass. Being different units with different physical
dimensions, they can never be 'equal'.
-- 47 lbs is the weight of 64.9 kgs of mass on Mars.
-- 47 lbs is the weight of 128.8 kgs of mass on the Moon.
-- 47 lbs is the weight of 21.3 kgs of mass on Earth.

Step-by-step explanation:
Answer:
Mass index for a 9-year-old child (at 82nd percentile
) = 22.51
Step-by-step explanation:
Given:
Mass index for a 9-year-old child = 18.4
Standard deviation = 4.5
Find:
Mass index for a 9-year-old child (at 82nd percentile
)
Computation:
At 82nd percentile,
p-value = 0.82
p-value from Z table score = 0.9153
Mass index for a 9-year-old child (at 82nd percentile
) = Mass index for a 9-year-old child + p-value from Z table score(Standard deviation)
Mass index for a 9-year-old child (at 82nd percentile
) = 18.4 + 0.9153(4.5)
Mass index for a 9-year-old child (at 82nd percentile
) = 18.4 + 4.11
Mass index for a 9-year-old child (at 82nd percentile
) = 22.51
47 = 50 - 3 or:
47 = Mean - 1 Standard deviation
For normal distribution it means that 4 bags represent 16 % of all samples.
4 bags ------ 16%
x bags ------ 100 %
---------------------------
4 * 100 = x * 16
16 x = 400
x = 400 : 16
x = 25
Answer: 25 bags were probably taken as samples.
