The question is asking to state how can you tell when a pattern shows counting on by tens, when you subtract the two number and there difference would be 10, that would be and an indicator. Hope i helped!

Using either the critical value rule or the p-value rule, if a one-sided null hypothesis for a single mean cannot be rejected at

KiRa [710]

Answer:

Step-by-step explanation:

Using either the critical value rule or the p-value rule, a conclusion can be drawn at a level of significance (alpha)

The null hypothesis: u = hypothesized mean

Alternative hypothesis: u > u0 or u < u0 for a one tailed test

Alternative hypothesis for a two tailed test: u =/ u0

To draw a conclusion by failing to reject the null hypothesis as stated then: using critical value

Observed z score > critical z score for both the one and two tailed test.

Or using p value:

P-value > alpha for a one tailed test

P-value > alpha/2 for a two tailed test

Thus, if a one-sided null hypothesis for a single mean cannot be rejected at a given significance level, then the corresponding two-sided null hypothesis will also not be rejected at the same significance level.

The weights, in pounds, of a group of student are as follows: 173 123 171 175 188 120 177 160 151 169 162 128 145 140 158 132 20

Akimi4 [234]

Mean: 160.12
Standard Deviation: 19.76
Median: 162
Maximum: 202
Minimum: 120

The mean is calculated by adding all of the numbers in the data set and dividing by the number of values that were added:

173 + 123 + 171 + 175 + 188 + 120 + 177 + 160 + 151 + 169 + 162 + 128 + 145 + 140 + 158 + 132 + 202 + 162 + 154 + 180 + 164 + 166 + 157 + 171 + 175 ÷ 25 = 160.12

Standard deviation is found by calculating the mean (160.12) , and then subtracting the mean and square root result for each number. Finally, working out the mean of the squared differences and taking the square root of the final answer results in a standard deviation of 19.76. (The attached image has the formula for finding standard deviation).

Median is the number that is found in the middle when placing the numbers in order from least to greatest.

The maximum is the largest number in the data set.

The minimum is the smallest number in the data set.

Identify the sets that contain 2 as an element. (Check all that apply.)Check All That Apply{2, 3, 4, 5, ...}{2, 3, 4, 5, ...}{0,

Lady bird [3.3K]

Question:

Identify the sets that contain 2 as an element. (Check all that apply.)

$A.\ \{2, 3, 4, 5, ...\}$

$B.\ \{0, 1, 4, 9, ...\}$

$C.\ \{2, \{2\} \}$

$D.\ \{\{2\}, \{\{2\}\}\}$

$E.\ \{\{2\}, \{2, \{2\}\}\}$

$F.\ \{\{\{2\}\}\}$

Answer:

$A.\ \{2, 3, 4, 5, ...\}$

$C.\ \{2, \{2\} \}$

Step-by-step explanation:

Required

For which of the options is 2 an element

$A.\ \{2, 3, 4, 5, ...\}$

The elements of this set starts from 2, then 3 and continues as thus.

Hence: 2 is an element

$B.\ \{0, 1, 4, 9, ...\}$

From the given elements in the above set, 2 is not listed.

Hence: 2 is not an element of this set

$C.\ \{2, \{2\} \}$

Here, 2 is listed as an element, 2 is also listed as a subset.

Since 2 is listed as an element, then 2 is an element of the set.

$D.\ \{\{2\}, \{\{2\}\}\}$

Here, 2 is listed as a subset of {2} and also as a subset of subset of {{2}}.

Since 2 is not listed as an element itself, then 2 is not an element of the set.

$E.\ \{\{2\}, \{2, \{2\}\}\}$

Here, 2 is listed as a subset of {2} and also as a subset of subset of {2,{2}}. This set only contains subsets, i.e. 2 is not listed as a direct element of the set.

Hence: 2 is not an element of the set

$F.\ \{\{\{2\}\}\}$

Here, 2 is listed as a subset of subset of {{2}}. This set only contains subsets, i.e. 2 is not listed as a direct element of the set.

Hence: 2 is not an element of the set
