Clearly the frequencies are starting from lower value 1 and increasing in a constant rate upto a highest frequency of 14 and then again decreasing in the same rate to the lower frequency of 1.
If we draw a bar diagram with the frequency we will get
Which shows that the distribution is approximately symmetric.
So the correct option is A
does the frequency distribution appear to have a normal distribution using the strict interpretation of the...

Do these costs appear to come from a population that has a normal distribution? Why or why not? Can the mean of your data sample be treated as a value from a population having a normal distribution? Why or why not? Did an “unusually low” or “unusually high” z-score value occur? Was the associated z score probability value less than 0.05 (p < 0.05); meaning a “significantly low” or “significantly high” event? If yes, what are the implications for the...
Question Hei Heights of aduilt males are known to have a norma distribution. A researcher claims to have randomly selected adult males and measured their heights with the resulting relative frequency distribution as shown here. Identify two major flaws with these resulits Relative Height (cm) F 23% 4% 130-144 145-159 160-174 2196 175-189 1. 16% - 190-204 Select all that apply A All of the relative frequencies appear to be roughly the same. If they are from a normal distribution...
Use the given categorical data to construct the relative frequency distribution. Natural births randomly selected from four hospitals in a highly populated region occurred on the days of the week (in the order of Monday through Sunday) with the frequencies 53, 63, 71, 57, 55, 46, 55. Does it appear that such births occur on the days of the week with equal frequency? Construct the relative frequency distribution Day Relative Frequency Monday Tuesday Wednesday Thursday Friday Saturday Sunday Type integers...

17.Find the standard deviation, s, of sample data summarized in the frequency distribution table given below by using the formulabelow, where x represents the class midpoint, f represents the class frequency, and n represents the total number of sample values. Also, compare the computed standard deviation to the standard deviation obtained from the original list of data values, 9.0. Standard deviation=___ Compare the computed standard deviation to the standard deviation obtained from the original list of data values, 9.0. Consider...

Hemmingway, Inc., is considering a $6 million research and development (R&D) project. Profit projections appear promising, but Hemmingway's president is concerned because the probability that the R&D project wlll be successful Is only 0.40. Furthermore, the president knows that even If the project successful, It will require that the company build a new production facility at a cost of $16 million in order to manufacture the product. If the facility is built, uncertainty remains about the demand and thus uncertainty...
