velikii [3]

Answer:

Null hypothesis (H_{0}): The birth weight of the first born of identical twins is the same as the birth weight of the second born.

Alternative hypothesis (H_{1}): The birth weight of the first born of identical twins is higher than the second born.

Step-by-step explanation:

Please note that the null hypothesis is the hypothesis we always want to reject or prove to be false. Hence in this study, the objective of the study is clearly stated that the researcher want  to determine whether the twin born first tends to weigh more than the twin born second.

Therefore, the null hypothesis we assume that the weight of the identical twins is the same regardless of who come first or last., while the alternative hypothesis is constructed or stated to answer the research objective.

In a class in which the final course grade depends entirely on the average of four equally weighted 100-point tests,
MAVERICK [17]

Answer:

  [8, 44]

Step-by-step explanation:

The average of equally-weighted values is their sum divided by their number.

<h3>Setup</h3>

For some fourth test score x, Paul wants an average between 70 and 79. This gives rise to the inequality ...

  70 ≤ (91 +88 +93 +x)/4 ≤ 79

<h3>Solution</h3>

Multiplying by 4, we have ...

  280 ≤ 272 +x ≤ 316

  8 ≤ x ≤ 44 . . . . . . . . . . subtract 272

Paul will get a C if his fourth test score is in the interval [8, 44].
