An operator of chocolate-packaging machine monitors the net weights of the packaged boxes by periodically weighing random sample

masya89 [10]

Answer: $H_0:\mu=453$

$H_1:\mu\neq453$

Step-by-step explanation:

Given : An operator of chocolate-packaging machine monitors the net weights of the packaged boxes by periodically weighing random samples of boxes.

The operator wishes to see if a random sample of 50 boxes gives evidence that the mean is different than 453 grams.

i.e. Claim : $\mu\neq 453$

We know that the null hypothesis is a kind of claim which always takes equals sign but alternative hypothesis does not.

Thus , the null and alternative hypotheses for the given situation will be :-

$\text{Null hypothesis}\ H_0:\mu=453\\\text{Alternative hypothesis}\ H_1:\mu\neq453$

What is the nearest tenth of 56.36

uranmaximum [27]

Answer:

56.4

Step-by-step explanation:

(a) 56.4 - 56.36 = 0.04

(b) 56.36 - 56.3 = 0.06

The difference is smaller for (a), so 56.36 is closer to 56.4.

The nearest tenth to 56.36 is 56.4.
