750 is ?% of 625

<em>Y = ?% * X</em>

Solving our equation for ?
?% = Y/X
?% = 750/625
? = 1.2

Convert decimal to percent:
<span>?% = 1.2 * 100 = 120%
</span>
Class 8 is 120% of Class 7.

If you want the percent of Class 8 to Class 7, it is:
 625 is ?% of 750

<em> = ?% * X</em>

Solving the equation for ?
?% = Y/X
?% = 625/750
? = 0.8333

Convert decimal to percent:
<span>?% = 0.8333 * 100 = 83.33%

</span>Class 7 is 83.33% of Class 8.

Some people took part in a game. The frequency shows information about their scores.
Marizza181 [45]

Answer:

The mean = 17.54

Step-by-step explanation:

Form a table as below;

<u>Interval         Frequency{f}      Midpoint of frequency{x}          fx    </u>

1-7                    19                         4                                            76

8-10                  14                         9                                            126

11-15                  15                         13                                           195

16-20                20                        18                                           360

21-35                 10                        28                                          280

36-50                13                         43                                          559

Sum                   91                                                                        1596

The mean  of grouped data = Sum of { Interval Midpoint * Frequency } /Sum of frequency

The mean= 1596 / 91

The mean = 17.54

nadezda [96]

Answer:

\mu_{p}=p=0.81

Step-by-step explanation:

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".  

The margin of error is the range of values below and above the sample statistic in a confidence interval.  

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

The population proportion have the following distribution

p \sim N(p,\sqrt{\frac{p(1-p)}{n}})

So under the null hypothesis the mean for the population proportion is p

\mu_{p}=p=0.81

And the standard deviationis given by:

\sigma_{p}=\sqrt{\frac{p_0(1-p_o)}{n}}=\sqrt{\frac{0.81(1-0.81)}{1000}}=0.0124
