Answer:

Word problems often produce a great amount of anxiety for students.

Bar diagrams clearly align with the four-step problem-solving plan.

• Students create a visual representation to demonstrate a clear understanding of  the problem.

  • The bar diagram requires students to identify the problem’s setting and the  values associated with the situation.

  • The completed bar diagram leads to a definitive solution plan.

  • The bar diagram can be used as a visual clue to determine the reasonableness of  the solution.

Combined with the values provided in the problem, a solution plan is revealed. After  solving the problem, the bar diagram can be used to check the solution by substituting the value into the  drawing and using logical reasoning to assess reasonableness.

If the level of significance (alpha) is 0.05, it means that the probability of rejecting the null hypothesis, when it is false,
Kaylis [27]

Answer: The probability of rejecting the null hypothesis, when it is true, is 5%.

Step-by-step explanation:

We know that the level of significance ( denoted as \alpha ) is generally the probability of rejecting the null hypothesis when it is true.

Therefore , If the level of significance (\alpha[/tex] ) 0.05, then it means that it is the probability of rejecting the null hypothesis when it is true.

i.e. The probability of rejecting the null hypothesis when it is true= 0.05

In percent : 0.05=5\%

Hence, the correct option is : The probability of rejecting the null hypothesis when it is true is 5%.
