Answer:
There is no sufficient evidence to support the claim that the bags are underfilled
Step-by-step explanation:
We are given;
n = 27 bags
Sample mean;X = 402 gram
Population mean;μ = 404 gram
Variance = 676
We know that, standard deviation(σ) = √variance
Thus;
σ = √676
σ = 26
The hypotheses are;
Null hypothesis; H0: μ = 404
Alternative hypothesis; HA: μ < 404
Let's find the z-score from the formula;
z = (X - μ)/(√σ/n)
z = (402 - 404)/√(26/27)
z = -2.04
From the z-distribution table attached, we have a p-value of 0.02068
This is less than the significance value of 0.01 and thus we will reject the null hypothesis and conclude that there is no sufficient evidence to support the claim that the bags are underfilled
Statement: 1) Triangle ABC
2) 2x 3)x=52
Reason: I’m not sure but probably addition
Yes....because a terminating decimal can be turned into a fraction, making it rational
Answer:
the other point could be 2.8
Step-by-step explanation:
in circle values of both x and are almost equal in magnitude
since 2.8 is closest to 3 i magnitude
hence 2.8 will be correct option
this point will lie in third coordinate
as third coordinate has points
(-x,y)
and coordinates of points lie on the circle are
(-3,2.8)
