Recall your hypotheses about the impact of the independent variables on the number of daily check-ins. Are there any coefficient

s that surprise you or contradict your original hypotheses? Develop a possible explanation for why the estimated coefficients might make sense in the context of the problem. Do the coefficients for payday or any of the holidays surprise you? What was your original hypothesis for those variables? Interpret the coefficients and explain why they support or contradict your intuition. Do any of the coefficients for day of the week surprise you? What was your original hypothesis for those variables? Interpret the coefficients and explain why they support or contradict your intuition. Do any of the coefficients for the number of rooms reserved on a given day to a particular type of guest (TotalRewards, SpecialEvent, VIP, FreeIndependent, Wholesale, Group) surprise you? What was your original hypothesis for those variables? Interpret the coefficients and explain why they support or contradict your intuition. Does the coefficient Rate surprise you? What was your original hypothesis for that variable? Interpret the coefficient and explain why it supports or contradicts your intuition.

AnnZ [12381]

Answer:

The median value is 47.

Step-by-step explanation:

First, organize the numbers in ascending order.

The median's position is calculated as ((N+1)÷2)th term, where N is the amount of data.

= 6÷2 th term

= 3 rd term

Answer:

There are 369 students who enrolled in either calculus or discrete mathematics.

Step-by-step explanation:

I'll create a Venn diagram to illustrate these figures.

Let’s define:

A represents the count of students who completed calculus.

B stands for those who took discrete mathematics.

We have the following:

$A = a + (A \cap B)$

Here, a denotes the students who studied calculus exclusively, while $A \cap B$ represents those who took both subjects.

Using the same reasoning:

$B = b + (A \cap B)$

There are 188 students taking both calculus and discrete mathematics.

This implies that $A \cap B = 188$

A total of 212 students studied discrete mathematics.

<pBased on this, $B = 212$

345 students have attended a calculus course.

<pSo, from this information, $A = 345$

We find the total number of students who took either calculus or discrete mathematics.

$(A \cup B) = A + B - (A \cap B) = 345 + 212 - 188 = 369$

A total of 369 students participated in either calculus or discrete mathematics.

Answer:

Step-by-step explanation:

Aligning each vocabulary term with its relevant example:

(1). All Americans = f. Population (a collective of items or subjects studied, e.g., residents of an area, the number of vehicles in a city, or employees in a workplace)

(2). The percentage of all Americans who strongly believe prisoners with life sentences who develop Alzheimer's should be released = c. Parameter (the figure summarizing a characteristic of a population)

(3). The percentage of the 85 surveyed Americans who strongly feel that prisoners with life sentences who have Alzheimer's should be released = d. Statistic (the characteristic of a sample that corresponds to a population parameter used for statistical inference)

(4). The responses being 'Strongly Agree', 'Agree', 'Disagree', or 'Strongly Disagree' = b. Variable (any measurable quality or characteristic)

(5). The 85 individuals surveyed = e. Sample (a subset of a population chosen based on certain criteria)

(6). The array of responses provided by the 85 participants = a. Data (the collected pieces of information meant for analysis)
