Answer: A) A boy is 19% more likely than a girl to own a dog than a cat or other animal.
Step-by-step explanation:
Here are the options:
A) A boy is 19% more likely than a girl to own a dog than a cat or other animal.
B) A boy is 33% more likely than a girl to own a dog than a cat or other animal.
C) A boy is 50% more likely than a girl to own a dog than a cat or other animal.
D) A boy is 52% more likely than a girl to own a dog than a cat or other animal.
Boy with a dog = 27
Total animals owned by boys = 27+15+10 = 52
Probability of owning a dog = 27/52 = 0.5192
Girl with dogs = 18
Total animals owned by girls = 18+25+12 = 55
Probability of owning a dog = 18/55 = 0.3273
Therefore, 0.5192 - 0.3273 = 0.1919 = 19.19%
Therefore, A) A boy is 19% more likely than a girl to own a dog than a cat or other animal.
Answer:
<h2> a. 1188 in.² </h2>
Step-by-step explanation:
Area of parallelogram is: A = B•H {H⊥B}
B = 36 in.
H = 33 in.
A = 36 in. • 33 in. = 1188 in.²
Answer:
t-value = 2.441
Step-by-step explanation:
Let's assume that this is a one-tailed test to calculate the critical value, the process is this:
- Calculate alpha (α): α = 1 - (confidence level / 100)
, but we already have this α=0.01
- Find the critical probability (p*): p* = 1 - α/2 = 1-0.005=0.995
- Then, the critical value would be shown as a t statistic, but for this we need:
degrees of freedom (df)= n-1=35-1=34
- The critical t statistic (t*) or critical value is the t-value having degrees of freedom equal to 34 and a cumulative probability equal to 0.995.
From the attached table we can see:
t-value = 2.441
