Answer (3)
Exercise it helps to reduce calories . eat healthy food helps u to stay fit. but active . eat sprouts everyday in the morning . drink plenty of water. u can be fit. hope this helped.
Fitness can be achieved through regular physical activity and a balanced diet. Engaging in at least 30 minutes of moderate exercise most days, along with consuming a variety of healthy foods and staying hydrated, is essential for maintaining fitness. Consistency and energy balance also play a crucial role in achieving fitness goals.

Berikut langkah-langkah dan hasil penyajian data nilai ujian statistika 100 mahasiswa ke dalam tabel distribusi frekuensi data berkelompok beserta perhitungan range dan banyak kelas interval: 1. Data nilai ujian (100 mahasiswa):36, 68, 83, 36, 67, 75, 57, 78, 84, 43, 51, 16, 68, 88, 83, 38, 89, 98, 87, 75, 67, 78, 85, 56, 67, 78, 86, 67, 71, 76, 79, 80, 70, 68, 90, 92, 80, 70, 63, 76, 48, 90, 92, 83, 83, 76, 61, 99, 83, 88, 88, 88, 89, 94, 46, 69, 99, 96, 68, 88, 47, 78, 85, 56, 67, 78, 86, 67, 74, 44, 36, 61, 18, 87, 76, 68, 88, 86, 63, 36, 49, 84, 71, 72, 35, 93, 91, 74, 60, 63, 80, 78, 73, 86, 88, 75, 81, 77, 63, 75 2. Menentukan Range (J)- Nilai maksimum (x_max) = 99 - Nilai minimum (x_min) = 16 - Range $$ J = x_{max} - x_{min} = 99 - 16 = 83 $$ 3. Menentukan banyak kelas interval (k)Gunakan rumus Sturges: $$k = 1 + 3.3 \log n$$Dengan $$ n = 100 $$, maka: $$k = 1 + 3.3 \times \log 100 = 1 + 3.3 \times 2 = 1 + 6.6 = 7.6 \approx 8 \text{ kelas}$$ 4. Menentukan panjang kelas interval (p)$$p = \frac{J}{k} = \frac{83}{8} = 10.375 \approx 11$$Untuk memudahkan, kita gunakan panjang kelas 11. 5. Menentukan batas kelas intervalMulai dari nilai minimum 16, kelas-kelas interval dibuat sebagai berikut:| Kelas Interval | Batas Bawah | Batas Atas ||----------------|-------------|------------|| 1 | 16 | 26 || 2 | 27 | 37 || 3 | 38 | 48 || 4 | 49 | 59 || 5 | 60 | 70 || 6 | 71 | 81 || 7 | 82 | 92 || 8 | 93 | 103 | 6. Menghitung frekuensi tiap kelasHitung jumlah data yang masuk ke tiap kelas:| Kelas Interval | Frekuensi (f) ||----------------|---------------|| 16 - 26 | 3 (16,18,16) || 27 - 37 | 6 (36,36,36,35,36,38) || 38 - 48 | 7 (38,43,44,46,47,48,49) || 49 - 59 | 5 (49,51,56,56,57) || 60 - 70 | 15 (60,61,61,63,63,63,63,67,67,67,67,68,68,68,69) || 71 - 81 | 18 (70,70,71,71,72,73,74,74,75,75,75,75,76,76,76,77,78,78) || 82 - 92 | 27 (78,78,79,80,80,81,83,83,83,83,83,84,84,85,85,86,86,86,86,87,87,88,88,88,88,88,89) || 93 - 103 | 19 (89,90,90,91,92,92,93,94,96,98,99,99) | 7. Tabel Distribusi Frekuensi Data Berkelompok| Kelas Interval | Frekuensi (f) | Frekuensi Kumulatif (F) ||----------------|---------------|-------------------------|| 16 - 26 | 3 | 3 || 27 - 37 | 6 | 9 || 38 - 48 | 7 | 16 || 49 - 59 | 5 | 21 || 60 - 70 | 15 | 36 || 71 - 81 | 18 | 54 || 82 - 92 | 27 | 81 || 93 - 103 | 19 | 100 | Jawaban singkat:a. **Range data** = 83 (nilai maksimum 99 - nilai minimum 16) b. **Banyak kelas interval** = 8 kelas (menggunakan rumus Sturges)
