Answer:
20 lizard lollies
Step-by-step explanation:
I attached the missing data.
Given the quantity of each treat below,
Swordfish sockers = 4
Lizard lollies = 10
Puffer pops = 6
From the figures above, the total number of treats is =
4 + 10 + 6 = 20
Since Martrix allows each participant to reach into his bag of goodies and select a treat, he then replaces it with the same treat and shakes the bag before offering a treat to another person. The probability a person picks lizard lollies will be:
Number of lizard lollies / total number of treats
Since the probability a person picks lizard lolllies is ½, If he then allows 40 people to choose a treat from the bag, the number of lizard lollies he can expect to give away will be:
½ * 40 = 20 lizard lollies
Answer:
a) 
So then we can conclude that the true proportion of women with cosmetic dermatitis from using eye shadow at 95% of confidence is between (0.0422 and 0.1410)
b) 
So then we can conclude that the true proportion of women with cosmetic dermatitis from using mascara at 95% of confidence is between (0.0628 and 0.1372)
c) For this case we see that both confidence intervals contains the value of 0.12 so then we can't conclude that only one group is referenced at the significance level of 0.05 used.
Step-by-step explanation:
Part a
The estimated proportion of women with cosmetic dermatitis from using eye shadow is given by:
The confidence interval is at 95% of confidence, our significance level would be given by 
and 
. And the critical value would be given by:
The confidence interval for the proportion is given by the following formula:
Replacing we got:
So then we can conclude that the true proportion of women with cosmetic dermatitis from using eye shadow at 95% of confidence is between (0.0422 and 0.1410)
Part b: A 95% confidence interval for the women with cosmetic dermatitis from using mascara
So then we can conclude that the true proportion of women with cosmetic dermatitis from using mascara at 95% of confidence is between (0.0628 and 0.1372)
Part c: Suppose you are informed that the true proportion with a nickel allergy for one of the two groups (eye shadow or mascara) is .12. Can you determine which group is referenced? Explain.
For this case we see that both confidence intervals contains the value of 0.12 so then we can't conclude that only one group is referenced at the significance level of 0.05 used.
Answer:
8 zlotys
Step-by-step explanation:
At Z32 per loaf, the demand will be ...
q = 381 -3(32) = 285 . . . . loaves
In order to produce 285 loaves, bakers must enjoy a price of ...
285 = 5 +7p
280/7 = p = 40 . . . . . zlotys per loaf
Since the loaves are sold for Z32, and bakers are expecting to be paid Z40, the subsidy they receive must be ...
Z40 -Z32 = Z8
The subsidy per loaf would have to be 8 zlotys.
Answer:
The most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 is 102
Step-by-step explanation:
We can build an estimate from a sample, and this estimate will be the best estimate for the proportion of the population.
Sample:
50 subscribers
15 own fewer than 2 vehicles
Proportion:
15/50 = 0.3 = 30% own fewer than 2 vehicles.
Based on the data, what is the most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 vehicles?
340 subscribers
The most reasonable estimate for this number is 0.3*340.
0.3*340 = 102
The most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 is 102
Answer:
Step-by-step explanation:
slope=change in y/change in x
one way is t pick 2 points, (x1,y1) and (x2,y2)
the slope is (y2-y1)/(x2-x1)
pick some points
(8,4) and (8,0)
slope=(0-4)/(8-8)=-4/0=undefined
the slope is undefined
there is no slope.
