- please do this by hand, not in excelA new type of crank for bicycles called the Powercam relies on a pushing motion rather than a circular motion. The company that markets this crank plans a test of five riders who will travel a 100-mile route once with the Powercam and once with a conventional crank. The company claims that the new crank reduces the time needed to cover the 100 miles. The times in hours for the five riders are 3. as follows: Rider 1 3 4 5 Powercam 4.4 4.6 4.7 4.8 4.9 Conventional 5.1 5.3 5.1 4.9 5.2 Use a 5% significance level and assume that both population distributions are normal. Is there sufficient evidence in the data to support the claim that the new crank reduces the time needed to cover the 100 miles? (Hint: Follow the steps 1) identify the case; 2) set the alternative hypothesis; 3) set the null hypothesis; 4) find the rejection region; 5) calculate the test statistic; and 6) make decision.)wk par- Adobe Acrobat Reader DC Fie Edit View Window Help Tools = المحاضرة الأولي، اpd Home Sign In O Q B 5 C x B Share 0.3390 0.2968 2 x ==(x3 + 1) Search Merge POr 3 0.2968 0,2932 2 Export POF 2 4 0.2932 0.2929 (x + 1) Adobe Export PDF X141 Convert PDF Files to Word 5 0.2929 0.2929 or Ecel Online .r = 0.2929 Select POF Fle ا المحاضرة الأولم Convert to H.W(1): Find the root of the function f(x) = 1-0.16 x which lies between [1.5, 2] Microsoft Word doo by using Simple Iterative Method work to 3-digits.

The concentration of mercury in fish tissue can be obtained by catching fish and sending samples to a lab for analysis. A study was conducted on fish from the Waccamaw and Lumber Rivers to investigate mercury levels in tissues of largemouth bass. At several stations along each river a group of fish were caught, weighed and measured; in addition a filet from each fish was sent to a lab so that the tissue concentration of mercury could be determined. In all, 171 fish were caught at 15 different research stations along the Waccamaw and Lumber Rivers. Data from fish caught at one of these stations is shown in the followinng table: length weight 1616 47.0 48.7 1862 2855 55.7 45.2 1199 1320 44.7 1225 43.8 870 38.5 1455 45.8 1220 44.0 1033 40.4 Compute the correlation between length and weight for these fish.
