Answer:

t < 10.2

Step-by-step explanation:

Step 1: Add 6.2 to both sides.

  • t - 6.2 + 6.2 < 4 + 6.2
  • t < 10.2

Therefore, the answer is t < 10.2.

Test the claim that the proportion of people who own cats is larger than 60 t the 0. 10 significance level?
Basile [38]

The null hypothesis to test the claim that the proportion of people who owns cats is larger than 60% of the significance level is H_{0}:μ<0.06.

Given that the significance level is 0.10.

We are required to form the null hypothesis to test the claim that the proportion of people who owns cats is larger than 60% the significance level.

Hypothesis is a statement which is tested for its validity. Null hypothesis is the statement which is accepted or not by z test,t test,f test ,chi-square test or any other test.

We have to take opposite of the statement to form a null hypothesis. Since we have to check whether the proportion of people who owns cats is larger than 60% of the significance level, we have to assume that it is smaller than 60% of the significance level.

60% of the significance level=0.60*0.10=0.06.

Null hypothesis is H_{0}:μ<0.06

Hence the null hypothesis to test the claim that the proportion of people who owns cats is larger than 60% of the significance level is H_{0}:μ<0.06.

Question is incomplete.The question should include the following:

Find the null hypothesis for the testing.

I'm confused need help :/

So slope intercept form is y=mx+b to convert this equation into slope intercept form we must make everything equal to y

3x-2y=7
3x=7+2y we add 2y to move it to the other side
3x-7=2y We subtract seven to have 1y by itself and then divide by two to get it into simplified slope intercept form
Answers=
3/2x-3.5=y or written as=
y=3/2x-3.5

<h3>Answer:  262,785</h3>

Note: you may need to delete the comma

============================================================

Explanation:

The info "5 months" is never used to compute the mean. We could easily replace it with "6 months" or "7 months" or any stretch of time, and still get the same answer. So we'll ignore this value.

What we'll do is add up the 21 items given to us, and then divide by 21.

Because there are so many values, and it's easy to get lost, I'm going to add up across the rows

  • Row One: 256,229+253,657+218,747+246,163+235,626+288,694 = 1,499,116
  • Row Two: 316,265+196,721+319,620+285,077+215,152+253,291 = 1,586,126
  • Row Three: 315,011+199,901+265,443+291,806+303,556+215,359 = 159,1076
  • Row Four: 258,554+293,658+289,935 = 842,147

Those subtotals then add up to this

1,499,116+1,586,126+1,591,076+842,147 = 5,518,465

This is the same as adding up all 21 values.

Finally, we divide that sum over 21 as there are 21 values in this list

(5,518,465)/21 = 262,784.047619048

That value then rounds up to 262,785

If your teacher just wanted things to the nearest whole number (without rounding up), then the answer would be 262,784

Side note: using a spreadsheet program would probably be the most efficient/fastest method for this type of problem.
