Answer:
a. The p-value is less than α, and the null hypothesis is rejected. There is not convincing evidence to support the claim that the proportion of books lasting at least 6 months when glued with G is different from the proportion of books lasting at least 6 months when glued with K.
Step-by-step explanation:
It is given that the library books are often glued for keeping the pages stick and intake. A glue is considered successful if it is able to make the pages of the book intake for at least six months.
It is given that the value of α is = 0.01
and the value of p is = 0.006
Thus when the p-value is less than the value of α, it results in the null hypothesis to get rejected. And there is no convincing support claim that the proportion of the books glued with G lasted for 6 months is different from the proportion of the books that lasted for 6 months when it is glued with K brand.
Answer:
15%
Step-by-step explanation:
180 x 15% = 27
Answer:Domain: all x-values that are to be used (independent values).
Step-by-step explanation:The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range. Domain: all x-values that are to be used (independent values).
Answer:
23/100 or 23/10
Step-by-step explanation:
2.3/1
(2.3 x 10) / (1 x 10) =23/10
find lcm (lowest common multiple) for 23 and 10
1 is the lcm for 23 and 10
23/10 is a simplest fraction for the decimal point number 2.3
Answer:
85
Step-by-step explanation:
add 4 values, excluding 72 (lowest grade)
total = 339
average = 330/4 = 84.75
84.75 rounding to nearest integer is 85
