Answer:
y=7, -3, 3, -9, 1 (in the empty boxes from left to right)
Step-by-step explanation:
Since y=x-2, all you have to do is take an x value from the top box and subtract 2 from that number to find the value of y.
Since
the 2nd equation has no solutions for x. So
Solution:
Answer:
P-value = 0.0261
We conclude that the machine is under-filling the bags.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 433 gram
Sample mean, = 427 grams
Sample size, n = 26
Alpha, α = 0.05
Sample standard deviation, σ = 15 grams
First, we design the null and the alternate hypothesis
We use one-tailed(left) t test to perform this hypothesis.
Formula:
Putting all the values, we have
Now, we calculate the p-value using the standard table.
P-value = 0.0261
Since the p-value is lower than the significance level, we fail to accept the null hypothesis and reject it.We accept the alternate hypothesis.
We conclude that the machine is under-filling the bags.
