None of the above:

Mean
10+29+15+29+35+2 = 120
120/6 = 20 is the mean

120+27 = 147
147/7 = 21 is the new mean

So mean increases by 1

Median
2 10 15 29 29 35
Write the numbers in order and find the middle number, there is no middle number

2 10 15 27 29 29 35
27 is the middle number

Mode
2 10 15 29 29 35
The repeated numbers are 29

2 10 15 27 29 29 35
The repeated number, your mode is 29

Let μ denote the true average reaction time to a certain stimulus. For a z test of H0: μ = 5 versus Ha: μ > 5, determine the

noname [10]

Answer: 0.0708

Step-by-step explanation:

Let μ denote the true average reaction time to a certain stimulus.

To determine : The P-value for a z test of H0: μ = 5 versus Ha: μ > 5.

In the given set of hypothesis , the alternative hypothesis is right -tailed , so the test is a right tailed test .

Given test statistic : a) z= 1.47

Now, the p-value for the right tailed test :

$P(z>1.47)=1-P(z\leq1.47)\ \ [\because P(Z>z)=1-P(Z\leq z)]$

$=1-0.9292=0.0708$

[Using the p-value table for z]

Hence, the required P-value = 0.0708

Answer:

Step-by-step explanation:

1) we have to find the area of the cut out portion

Since both circles in one side makes up the side 28cm

The diameter of each circle is 14cm

radius = diameter / 2

r = 7cm

Area of a circle = πr²

A = 22/7 × 7²

= 22/7 × 7 × 7

= 22 × 7 = 154cm²

So the four circles will make

= 154 + 154 + 154 + 154

= 616 cm²

The Area of the square will be

= L × L

= 28 × 28

= 784 cm²

Therefore the area of the remaining portion will be

Area of the square - total area of the circles

= 784 cm² - 616 cm²

= 168 cm²

The area of the remaining part is 168 cm²
