We are continuing to study the difference in average time for completion for the two matching schemes. However, this time we had

30 individuals participate. The shapes and cutouts are all the same color (treatment s) The shapes and cutouts are different colors (treatment d) For each participant, the treatment s - treatment d was found. The 95% CI was (-4.617, -9.383). Complete the interpretation statement. "We are 95% confident that the time to completion for the same color method is between 4.617 to 9.383 than the different color method."

Answer:

We are 95% confident that the time to completion for the same color method is between 4.617 <u>less</u> to 9.383 <u>less</u> than the different color method.

Step-by-step explanation:

The (1 - α)% confidence interval for population parameter implies that there is a (1 - α) probability that the true value of the parameter is included in the interval.

Or, the (1 - α)% confidence interval for the parameter implies that there is (1 - α)% confidence or certainty that the true parameter value is contained in the interval.

The 95% confidence for the difference in the completion time of treatment is<em> and </em>d<em> is,</em>

<em>CI</em><em> = </em>(-4.617, -9.383)

The parameter of the study is defined as:

treatment_<em>s - </em>treatment_<em>d </em>

Consider the 95% confidence interval, (-4.617, -9.383). The confidence interval consists of all negative values.

This implies that the difference between the completion time of treatment <em>s</em> and <em>d</em> is less than 0, i.e. the completion time of treatment <em>s</em> is less than that for treatment <em>d</em>.

Thus, the complete statement is:

"We are 95% confident that the time to completion for the same color method is between 4.617 <u>less</u> to 9.383 <u>less</u> than the different color method."

Hey there (again)

x = 2y  \\ y = -2  \\ x = 2(-2) \\x= -4 \\ \\ \\ w + xy + 4x^2  = 2\\ w+-4(-2) + 3(-4)^2 = 2 \\ w + 8 + 3(16) = 2 \\ w + 8 + 48 = 2 \\ Subtract56: w + 56 =2 \\ 56 - 56 (Cancel) \\ 2 - 56 = -54 \\ w = -54

Answer: B  the simplification performed in step 2 is invalid or incorrect

Good luck on your assignment and enjoy your day

7. What is the cardinality of each of the following sets?
zysi [14]

Answer:  

The cardinality of set (a) is 0,

the cardinality of set (b) is 1

and

the cardinality of set (c) is 3.

Step-by-step explanation:  We are given to find the cardinality of each of the following sets :

(a) { }.

(b) { { } }.

(c) {a, {a}, {a, {a}} }.

We know that

CARDINALITY of a set is the number of elements present in the set.

(a) The given set is A = { }.

The set A is an empty set, so it does not contain any element. Hence, the cardinality of the set A is 0.

(b) The given set is B = { { } }.

The set is B is singleton set, contains only one element (that is empty set). So, the cardinality of the set B is 1.

(c) The given set is C = {a, {a}, {a, {a}} }.

The set C has three elements, a, the set {a} and the set {a, {a}}. So,  the the cardinality of set C is 3.

Thus,

the cardinality of set (a) is 0,

the cardinality of set (b) is 1

and

the cardinality of set (c) is 3.
