Consider the idea of a sampling distribution in the case of a very small sample from a very small population. The population is 10 students in a certain class: Student 1 4 7. 8. 9. Weight 136 99 118 129 125 170 130 128 120 147 The mean weight in pounds u in this population is the parameter of interest. la) Finish filling in the frequency distribution table: Counts (Frequency) 90-109.9 1 110-129.9 130-149.9 150-169.9 170-179.9 Total: 10 1b) Find the population mean u.

Use the indicated data to construct the frequency distribution. Weights of respondents were recorded as part of the California Health Interview Survey. The last digits of weights from 50 randomly selected respondents are listed below. Construct a frequency distribution with 10 classes. Based on the distribution, do the heights appear to be reported or actually measured? What do you know about the accuracy of the results? 5  0  1  0  2  0  5  0  5  0  3  8  5  0  5  0  5  6  0  0  0  0  0  0  8 5  5  0  4  5  0  0  4  0  0  0  0  0  8  0  9  5  3  0  5  0  0  0  5  8 PLEASE SHOW ALL WORK!!!

A sample of 15 boy scouts was selected and their weights (in pounds) were recorded in the table below. Construct a frequency distribution to answer the following questions. 97 120 137 124 117 108 134 126 123 106 130 110 100 120 140 a. Using the class width of 10 give the upper and lower limit for five classes, starting with lower limit of 95 for the first class b. Construct a frequency distribution for the data

Need help with parts C & D The proportion of Americans who have frequent migraines is 15.2% according to the CDC. An acupuncturist claims that her treatment can reduce this figure significantly. A random sample of 191 Americans is administered the acupuncturists treatment and 25 report experiencing migraines.a. State Hypotheses to the scenario using the correct symbols. b. What is the sample proportion? (Round to 2 decimal places) ˆpp^= c. Suppose the P-value is calculated to be 0.0318What would your decision be for this test using α=α= 0.025? fail to reject the null accept the null reject the null d. Write a conclusion in terms of the acupuncturist's claim. Use the model provided by the instructor. Assume no errors were made.

In a survey of 35 families in a village, the number of children per family was recorded and the following data obtained: 1 0. 3 4 5. 6. 7. 8 2 3. 4 0. be ries ring 8. 4 12 6. 3. 6. 3 3. 7. 8. 6. 7. 9. 4 3 Represent the data in the form of a discrete frequency distribution. 2. 4- 5 5

Examine the frequency distribution. What is the width of a class in this frequency distribution? Enter your answer as a number, like this: 42

Construct a frequency distribution for the data using five classes. Describe the shape of the distribution. The ages of dishwashers (in years) in 20 randomly selected households are shown below. 9 13 5 15 12 6 4 9 11 1 7 898 7 6 8 8 21 OA. bell shaped OB. skewed to the left OC. skewed to the right O D. uniform
