Out of 165 samples of travelers collected from country Sri Lanka we found that 23 of the people travelled to USA during the pandemic era. Similarly we sampled 279 travelers from India and found that 86 of them travelled to USA during pandemic era. Consider travel to USA as success. Find the pooled sample proportion.

Random samples were collected from the state of Ohio and Indiana regarding the number of people being vaccinated daily at certain hospitals. Check the claim if the variance in both cases differ or not? The sample variance for the 109 samples collected from Ohio is 4.389 and the sample variance for 94 samples collected from Indiana is 5.275.  Find the test statistic. [TESTSTATISTIC] (approximate upto 3 decimal places) Find the df of the distributions of the test statistic. [DF1][DF2]

Fifty-four wild bears were​ anesthetized, and then their weights and chest sizes were measured and listed in a data set. Results are shown in the accompanying display. Is there sufficient evidence to support the claim that there is a linear correlation between the weights of bears and their chest​ sizes? When measuring an anesthetized​ bear, is it easier to measure chest size than​ weight? If​ so, does it appear that a measured chest size can be used to predict the​ weight? Use a significance level of α=0.05. r : 0.956 Critical r = + – 0.268 P Value : 0.000 Determine the Ho. [Rho] Identify the correlation coefficient.[r] Is there sufficient evidence to support the claim that there is a linear correlation between the weights of bears and their chest​ sizes?  Use correlation coefficient as the test statistic.
