This lab is on single sample t-test. This is ALL the relevant information given, including the data needed for the lab. The questions are answered using the program Jamovi, which i put down bellow to download. The worksheet has questions and steps that you answer using the program (you don't submit nothing on the program, you are simply using it for statistical calculations).

Please if a tutor can at least try to help me out I urgently need help please!!.

This is the link you can use to download the program

Here is the worksheet.

Lab Analysis Report #5: Single-Sample t-test Instructions: You will complete this lab report using Jamovi statistical software package. The data are in google sheet . 1. An assumption of the t-test is that your sample was obtained randomly, however, for the questions in this lab, we are going to be using your data -- data from students enrolled in Drew's COGS 148 class. If we actually wanted to draw conclusions about the UCSD population more generally, what would be a better way to collect this data? Briefly describe how you might collect this data. Now, with that out of the way, we are going to pretend we took a random sample, perhaps in the the way you described above. 2. Members of Gen Z (those born between late 90s and early 2010s), on average received their first smartphone when they were 10.3 years old. According to our class data, do we have evidence that UCSD students are different from Gen Z in the U.S. population more generally? a. What is the null hypothesis? b. What is the alternative hypothesis? C. Using smartphone data conduct the appropriate type of t-test in JAMOVI to see if there is evidence for her hypothesis. Paste an image of the table output below. d. Should we retain or reject the null hypothesis? Assume an alpha of .05.e. Write a sentence as it would appear in the results section of a journal article describing the outcome of your statistical test. f. given the outcome of your statistical test, what type of error is possible? 3. In a Gallup Poll conducted in Fall 2020 Americans were asked "How worried are you that you will get coronavirus?" On a scale of 1 (Very worried) to 4 (Not at all worried), and the average response was 2.6 (assume this is an actual population parameter even though it is just a very large sample). According to our class data (which we'll assume is a random sample from the American population), do we have evidence that people now feel differently from then the population felt two years ago? a. What is the null hypothesis? b. What is the alternative hypothesis? c. Using Worried data conduct the appropriate type of t-test in JAMOVI to see if there is evidence for her hypothesis. Paste an image of the table output below. d. Should we retain or reject the null hypothesis? e. Write a sentence as it would appear in the results section of a journal article describing the outcome of your statistical test.f. given the outcome of your statistical test, what type of error is possible? 4. According to a statistic released by Instagrams this year, the average instagram account owner has 150 followers. Do we have evidence that UCSD students are more or less popular on twitter than the population average? a. What is the null hypothesis? b. What is the alternative hypothesis? c. Using InstaFollower data conduct the appropriate type of t-test in JAMOVI to see if there is evidence for this hypothesis. Paste an image of the table output below. d. Should we retain or reject the null hypothesis? e. Write a sentence as it would appear in the results section of a journal article describing the outcome of your statistical test. f. given the outcome of your statistical test, what type of error is possible?Subject# AgeSmartF Worried InstaFollowers 12 1000 11 700 12 605 8 35 WAWWANNO O DONOVAN 500 15 38 12 14 594 15 1060 10 1472 11 16 250 12 12 1331 13 14 13 556 15 13 90 16 13 21 17 12 NNWAWAN 800 18 19 8 300 20 14 300 21 22 12 3 144 23 24 13 319 25 1083 26 16 0 27 16 410 28 15 40029 30 14 599 31 13 668 32 13 454 33 14 34 13 246 35 13 479 36 12 85 37 12 268 38 12 961 39 40 41 11 153 42 12 391 43 44 12 250 45 15 480 46 13 1217 47 12 1030 48 13 AWWNN- NOW WA OO OO 219 49 14 811 50 13 51 52 15 53 12 428 54 12 55 56 13 350 57 17 0 5859 15 784 0 N 60 17 0 61 62 10 3 84 63 11 1081 64 12 65 14 313 66 12 1249 67 13 NWAWWAD 475 68 16 150 69 14 715 70 13 607 71 72 12 30 73 74 13 174 75 14 1021 76 77 12 78 12 1180 79 12 339 80 16 36 81 10 952 82 13 200 83 13 498 84 12 1213 85 12 196 86 14 659 87 88 389 12 580 90 12 505 91 13 1000 92 10 833 93 16 589 94 12 85 95 96 15 481 97 17 389 N N NADO WA WA WO WO AWW 98 7 570 99 15 500 100 14 0 101 13 880 102 9 300 103 12 750 104 13 700 105 13 106 8 287 107 108 3 109 14 110 13 1145 111 12 1460 112 1458 113 10 682 114 12 1333 115 14 526 116 13 569 117 12 707 118 14 319\f149 18 488 150 12 151 152 14 167 153 16 50 154 13 702 155 8 700 156 14 650 157 14 156 158 159 12 3 500 160 161 13 1700 162 16 163 164 10 0 165 10 166 167 17 506 168 13 400 169 10 1000 170 12 171 14 WAN- NOANOA ONNADOWOOD N 80 172 173 12 300 174 9 175 15 176 14 320 177 15 300 178 11 545 179 11 1420 180 10 510 181 15 0
