Hope i helped have a wonderful day...can i get a Brainliest please and thank you...
Here you go :) have a good day
c: number of carnations
r: number of roses
Rebecca's expression is
r = c + 4
Replacing with the values of the table:
c | r
0 | 0+4 = 4
1 | 1+ 4 = 5
2 | 2+4 = 6
3 | 3+4 = 7
4 | 4+4 = 8
Then, Rebecca is correct.
Isolating c from Rebecca's expression:
c = r - 4
which is Austin's expression. Then, Austin is correct too.
Answer
given,
mean = 12 Kg
standard deviation = 0.5 Kg
assume the observed statistic is = 11.1
now, 
assuming the number of sample = 4
n = 4
Hypothesis test:
H₀ : μ≥ 12
Ha : μ < 12
now,
significant level α = 0.05
z* = -3.60
Test statistics, Z* = -3.60
P-value
P(Z<-3.60) = 0.002 (from z- table)
P- value = 0.002
now,
reject the value of H₀ when P-value < α
0.002 < 0.05
since, it is less P-value < α , we have to reject the null hypothesis
Answer:
The answer is B
