Answer:
a) P-value = 0.0968
b) P-value = 0.2207
c) P-value = 0.0239
d) P-value = 0.0040
e) P-value = 0.5636
Step-by-step explanation:
As the hypothesis are defined with a ">" sign, instead of an "≠", the test is right-tailed.
For this type of test, the P-value is defined as:
being z* the value for each test statistic.
The probability P is calculated from the standard normal distribution.
Then, we can calculate for each case:
(a) 1.30
(b) 0.77
(c) 1.98
(d) 2.65
(e) −0.16

Answer:
58%
Step-by-step explanation:
We need to find what percent 290 is of 500.
percent = part/whole × 100%
percent = 290/500 × 100%
percent = 58%
Answer: 58%
Let the total cost of the item be represented by C and the price be represented by P, then given that t<span>he total cost of an item including sales tax is directly proportional to its price, thus</span>
where k is a constant.
Given that <span>the total cost of a $32 item is $33.60, thus
Therefore, the total cost on a $55 item is given by
</span>
Answer: The shoe size would be recommended for a four-month-old baby is equal to 1
Step-by-step explanation:
Since, according to the given figure,
Here, x represents age of baby (in month) while y represents shoe size.
And for babies , 
the shoe size = 0
the shoe size = 1
the shoe size = 2
the shoe size = 3
the shoe size = 4
thus, from the above we can say that, the shoe size of the baby who is 4 month old is 1.
