A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 432 gram setting. It
vova2212 [387]

Answer:

-2.154

Step-by-step explanation:

We are given;

Population mean; μ = 432

Sample mean; x¯ = 425

Sample size; n = 29

standard deviation; σ = 26

Hypothesis is defined as;

Null hypothesis; H0: μ ≥ 432

Alternative hypothesis: Ha: μ < 432

Formula for the test statistic since sample size is less than 30 is;

t = (x¯ - μ)/(σ/√n)

Plugging in the relevant values;

t = (425 - 432)/(26/√29)

t = -1.45

Now,we are given significance level of 0.02; our DF = n - 1 = 29 - 1 = 28

From t-table attached, we can see that at DF of 28 and significance value of 0.02, the critical value is 2.154

However, this is a left tailed test as the rejection region is to the left.

Thus, the critical value of a left tailed test is negative. Thus, in this case our critical value will be -2.154

Lesechka [4]

Complete Question

Marla sawed a 12-meter wood plank into 8 equal pieces. Which statement best explains how Marla cut the wood plank?

a) She cut the wood into pieces that are each 1/3 meter long.

b) She cut the wood into pieces that are each 1/2 meter long.

c) She cut the wood into pieces that are each 1 meter long.

d) She cut the wood into pieces that are each 1 1/2 meter long.

Answer:

d) She cut the wood into pieces that are each 1 1/2 meter long.

Step-by-step explanation:

Marla sawed a 12-meter wood plank into 8 equal pieces.

Hence,

8 equal pieces = 12 meter

1 equal pieces = x meter

Cross Multiply

8 × x = 1 × 12

x = 12/8 meters

x = 3/2 meters long

x = 1 1/2 meters long.

Therefore, Option d is the correct Option
