In this lab‚ we tested the effect of flame on different chemical solutions. In order to do this‚ we used a wooden stick soaked in a metal and nonmetal solution‚ hovered it over a bunsen burner‚ and recorded the color that the flame changed to. The seven solutions we tested were lithium chloride‚ strontium chloride‚ calcium chloride‚ sodium chloride‚ barium chloride‚ copper chloride‚ and potassium chloride. However‚ we had another four additional solutions‚ which had unknown chemical composition

(3) Example: We want to measure the monthly sales volume from Microsoft and Apple. We collect data for a year ( 12 months). We calculate the variance for both and define the “degrees of freedom’ (n-1= 11) and then we can build the F-distribution. F statistic (): Defined as the ratio of the dispersions of the two distributions‚ in other words it is the value calculated by the ratio of two sample variances . F always >=1. The F statistic can test the null hypothesis: (1) that the two sample

Hypothesis Testing Paper Team A PSY/315 July 7‚ 2014 Instructor: Regina Pendergrass Inside statistics‚ it has to be understood what hypothesis testing is to find and verify research to be studied. Hypothesis testing is a form of research that is used to show how a certain issue will end or how the researcher(s) think the issue will end in the environment that it is situated. The testing will show that even though an answer may form‚ it does not prove the answer is correct secondary to the

occupied by aggregates. One of the physical properties of aggregate that influence the property of concrete is the grading of aggregate. The grading of aggregate defines the proportions of particles of different size in the aggregate. The grading of fine (size < 5 mm) and coarse (size > 5 mm) aggregates are generally required to be within the limits specified in BS 882: 1992. OBJECTIVE The objective of this experiment is to obtain the grading curve for both fine and coarse aggregate.

The Charpy impact test‚ also known as the Charpy V-notch test‚ is a high strain-rate test which determines the amount of energy absorbed by a material during fracture. The Charpy test specimens were made according to the dimensions of standard ASTM A370. One of the main reasons for concern for natural composites laminates generally is the low values

Cold pressor test is widely used as test for auto- nomic functions. It has been used as diagnostic test for diseases like hypertension and other cardiac auto- nomic disorders. During cold pressor test ‚ the hand or foot is immersed in cold water bath held at a con- stant temperature at 80 C. Cold water immersion activates afferent pain and temperature neurons‚ re- sulting in a centrally mediated stimulation of sympa- thetic efferent neurons. In healthy subjects ‚ the CPT causes increase

accordance with the requirement of MBA course this report is been drafted. Being MBA students we got great opportunity to understand the applications of Primary and secondary data collection and interpretation. We came to know about practice use various statistical tools and methods like chi-square‚ ANNOVA‚ sample size calculator etc. We also got experiences of drafting questionnaire‚ field work to get questionnaire filled.
