Question

в кафе "пицца" в течении 15 дней фиксировалось количество заказов с доставкой на дом. получили такой данных:40,34,46,26,34,41,48,39,35,34,41,45,46,33,28 найдите размах,сред.ариф.,моду и медиану полученного ряда​

Answer 1

Размах = 48 - 26 = 22

Сред. арифметическое = (40 + 34 + 46 + 26 + 34 + 41 + 48 + 39 + 35 + 34 + 41 + 45 + 46 + 33 + 28)/15 = 34,8

Мода = 34

Медиана = 39

Answer 2

Calculating Measures for the Given Data

To find the range, mean, mode, and median of the given series of delivery orders over a 15-day period, we can use the following steps:

1. Range: The range is the difference between the maximum and minimum values in the data set. In this case, we have the following data points: 40, 34, 46, 26, 34, 41, 48, 39, 35, 34, 41, 45, 46, 33, 28. The maximum value is 48, and the minimum value is 26. Therefore, the range is 48 - 26 = 22.

2. Mean (Average): The mean is calculated by summing up all the values in the data set and dividing by the total number of values. In this case, we have 15 data points. By adding up all the values and dividing by 15, we can find the mean. The sum of the data points is 40 + 34 + 46 + 26 + 34 + 41 + 48 + 39 + 35 + 34 + 41 + 45 + 46 + 33 + 28 = 570. Therefore, the mean is 570 / 15 = 38.

3. Mode: The mode is the value that appears most frequently in the data set. In this case, we can see that the value 34 appears three times, which is more than any other value. Therefore, the mode is 34.

4. Median: The median is the middle value in a sorted data set. To find the median, we need to sort the data set in ascending order. The sorted data set is 26, 28, 33, 34, 34, 34, 35, 39, 40, 41, 41, 45, 46, 46, 48. Since we have an odd number of data points (15), the median is the value in the middle position, which is the 8th value. Therefore, the median is 35.

To summarize, the measures for the given data set are as follows: - Range: 22 - Mean: 38 - Mode: 34 - Median: 35
