Answer:
$142 ; 0.749 ; Normal ; 0.090938
Step-by-step explanation:
Mean and standard deviation :
The mean of the distribution x = $142, because the sample size is sufficiently large, the distribution will be approximately normal (central limit theorem).
Standard deviation of distribution : σ/ sqrt(n)
= 29 / sqrt(1500)
= 0.749
B.)
Shape of sampling distribution of X.
The shape of the sampling distribution will be approximately normal due to the large sample size used. This is according to the central limit theorem whereby distribution of sample converges to normal with increasing sample size. Mean ~ N(142, 0.749²)
C.)
P(X > 143)
Using the relation :
Z = (x - mean) / standard error
Z = 143 - 142) / 0.7489
Z = 1.335
P(Z > 1.335) :
Using the Z probability calculator :
P(Z > 1.335) = 0.090938
the answer could be D 5 units
because the distance between B and C is 5 by looking at the x-axis
Step-by-step explanation:
Number of pork chops Mrs Spina bought =
Number of boxes x number of pork chops per box
= 4x8
= 32
Number of Pork chops to freeze = 32 - 12 (set aside) = 20
Number of packs of pork chops to freeze = Number of pork chops to freeze / pork chops per pack
= 20/4
= 5 packs.

An outglier is a data item which is much bigger/smaller than other data items.
The data item arranged is 0.7, 3.1, 4.3, 5.2, 5.3, 5.4, 5.6, 5.8
From the data 0.7 is much smaller than other data items.
