Will the researcher reject the null​ hypothesis? A. Do not rejectDo not reject the null hypothesis because muμequals=35.135.1 mi
lozanna [386]

Apparently the questionnaire is incomplete, then the first part necessary to solve the question is left

The average daily volume of a computer stock in 2011 was

muμequals=35.135.1

million​ shares, according to a reliable source. A stock analyst believes that the stock volume in 2014 is different from the 2011 level. Based on a random sample of

3030

trading days in​ 2014, he finds the sample mean to be

30.330.3

million​ shares, with a standard deviation of

sequals=12.612.6

million shares. Test the hypotheses by constructing a

9595​%

confidence interval. Complete parts​ (a) through​ (c) below.

Answer: however, with the given options we can say that the correct option is "B", in which the value of the confidence interval is necessary to accept or reject the null hypothesis, we deduce that the value is not in the confidence interval so it must be rejected

Which of the following is true about multi-collinearity? Group of answer choices The P-value reduces significantly, leading to r
julsineya [31]

Answer:

It is measured using a measure called variance inflation factor (VIF).

Step-by-step explanation:

This is the statement that is true about multi-collinearity. Multi-collinearity is a situation that can sometimes arise when dealing with a multiple regression model. Multicollinearity refers to the occurrence of high intercorrelations among various independent variables. This can often lead to results that are skewed or misleading. The main way in which multi-collinearity can be measured is by using the variance inflation factor (IVF). This allows us to quantify the severity of multi-collinearity.

Determine whether the origin is included in the shaded region and whether the shaded region is above or below the line for the g
kati45 [8]

Answer:

Option: D is correct.

Step-by-step explanation:

since we are given a inequality as:

y

Clearly from the graph of the following inequality we could see that the origin is included in the shaded region and the shaded area is below the line.

Also it could be seen that if we put the origin points i.e. (0,0) in the inequality than 0<2 and the condition is true and hence origin is included in the shaded area.

Hence, option D is true.
