A random sample of 12 song lengths (in minutes) on a playlist found: = 278.3, s = 19. Build a 80% CI for the population mean length of a song on the playlist. Round all intermediate calculations to two decimals, then construct the Cl and enter like this: (min,max). Note: if you use a built-in Cl command on a calculator/computer, you might get marked wrong due to rounding. Use the formulas given in the text/notes. a. Since n < 30, We use a Z-interval O We use s, not o O It is important that song lengths be normally distributed O We use a T-interval b. The Cl is: Submit Question
For healthy adults, the mean pH of arterial plasma (i.e., acidity of the blood) is 7.4. A new drug for arthritis has been developed. Researchers want to conduct a test to see if the new drug has increased the mean pH level of the blood. A random sample of 91 patients with arthritis took the new drug for 3 months. An analysis of the sample data revealed a p-value of 0.019. Step 3 of 3: Use a 1% level of significance to test the claim that the drug has increased the mean pH level of the blood.

Good morning, I have some doubts about this. I would appreciate your help to clarify them. To determine the observed frequencies, I took the data and created a table with some intervals as follows: 1). Determine the maximum value, minimum value, range, number of intervals and amplitude. Which gave me the following: Maximum value=9.7 ; Minimum value=0.2Range=maximum value-minimum value=9.7-0.2=9.5Número de intervalos=1+(3,3222*LOG(n))=1+(3,3222*LOG(50))=6.64Amplitude=(Maximum value-minimum value)/(Number of intervals)=(9.7-0.2)/6.64= 9.5/6.64=1.43 With this, determine the intervals of the data table and then according to those intervals take out the observed frequencies for those intervals, as follows: Intervals (Minutes) / Observed frequencies (Oi)[ 0,20 - 1,63 ] / 18[ 1,64 - 3,07 ] / 10[ 3,08 - 4,51 ] / 8[ 4,52 - 5,95 ] / 6[ 5,96 - 7,39 ] / 4[ 7,40 - 8,83 ] / 2[ 8,84 - 10,27] / 2 Then, with these observed frequencies find the exponential probabilities as follows: Probabilities (I…
