Please do not give solution in image format thanku A car salesman collected data on how many cars were sold at a dealership per day for two weeks. The results were as follows: 6, 7, 4, 3, 1, 2, 6, 6, 6, 7, 4, 4. Make a frequency table and then make a histogram based on that frequency table. What is the shape of the distribution? O Skewed to the right O Skewed to the left O Bimodal O Symmetrical

Determine whether the given value is a statistic or a parameter.   A homeowner measured the voltage supplied to his home on 23 days of a given month​, and the average​ (mean) value is 143.1 volts.   Part 1 Choose the correct answer below.     A. The given value is a statistic for the month because the data collected represent a population.   B. The given value is a parameter for the month because the data collected represent a sample.   C. The given value is a parameter for the month because the data collected represent a population.   D. The given value is a statistic for the month because the data collected represent a sample.

The Ahmadi Corporation wants to increase the productivity of its line workers. Four different programs have been suggested to help increase productivity. Twenty employees, making up a sample, have been randomly assigned to one of the four programs and their output for a day's work has been recorded. You are given the results below. At 95% confidence, conduct the ANOVA test to determine whether there is a significant difference in the mean output under the four programs.
