Descriptive Statistics

Descriptive statistics involve organizing, summarizing, and presenting data in a meaningful way. This includes measures such as:

  • Sample mean (x̄)
  • Frequency distributions
  • Relative frequency
  • Cumulative relative frequency
  • Box plots

Inferential Statistics

Inferential statistics involve making conclusions and inferences about a population based on a sample of data. This includes concepts such as:

  • Population and sample
  • Parameter and statistic
  • Variable

Statistical Inference: Hypothesis Testing and Confidence Intervals

Chapter 17: Inferences When Standard Deviation is Unknown

Big Idea: T-Test for Unknown Standard Deviation

The t-test is used when the population standard deviation (SD) is unknown. It has fewer conditions than z-tests for inferences about a mean:

  • Data is a simple random sample (SRS) from a larger population.
  • Observations follow a normal distribution.
  • We estimate standard error using s / √n, where s is the sample SD and √n accounts for the variability of sample means.

Problem #B-1: Simultaneous Equations for Optimization

a. Maximize Z = 4×1 + 3×2

Subject to:

Material: 6×1 + 4×2 <= 48 lb (x1 = 2)

Labor: 4×1 + 8×2 <= 80 hr (x2 = 9)

x1, x2 >= 0 (Profit = 35)

b. Maximize Z = 6A + 3B

Subject to:

Material: 20A + 6B <= 600 lb (A = 24)

Machinery: 25A + 20B <= 1000 hr (B = 20)

A, B >= 0 (Profit = 204)
