Suppose that the sitting back-to-knee length for a group of adults has a normal distribution with a mean of μ = 23.5 in. and a standard deviation of σ = 1.1 in. these data are often used in the design of different seats, including aircraft seats, train seats, theater seats, and classroom seats. instead of using 0.05 for identifying significant values, use the criteria that a value x is significantly high if p(x or greater) < _ 0.01 and a value is significantly low if p(x or less) < _0.01. find the back-to-knee lengths separating significant values from those that are not significant. using these criteria, is a back-to-knee length of 25.6 in. significantly high?

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

they can both be solutions depends on the equation
